shells/nushell: update to 0.71.0

 - New ++ operator (merelymyself)
   In this release, you can now use the ++ operator to append lists together.
   For example, you can combine two lists into a new lists made up of the both
   lists.
   Note: Currently, this operator cannot be used to join two tables. This
   functionality is still being worked on and will likely be present in the
   next version.
 - Improved consistency across commands and types
   Nushell continues improve quality of the language and shell with a set of
   consistency improvements in this release. These include:
    - More iterating filter commands now support the $in variable consistently
      (webbedspace)
    - Lists now support upsert (fdncred)
    - merge can now also operate on records (webbedspace)
    - str substring can take ranges (rgwood)
    - from and to now show help info (rgwood)
 - Right prompts can now be on the last line (nibon7)
   Previously the right prompt appeared only on the same line where the user
   input started. Now you can choose to place the right prompt part on the last
   line of user input. This feature is not enabled by default, you can enable
   it using the config nu command to modify the config.nu file, just set
   render_right_prompt_on_last_line to true.
 - Configuring the default value viewer via display_output hook (perbothner)
   You're now able to configure a new hook, called display_output, which will
   become the default way that you view data.
   Using this, you can for example, use table --expand to always see fully
   expanded tables.
   If your terminal supports it, you can this to render a more full-featured
   output. For example, DomTerm could be used by setting the display_output
   hook to: to html --partial --no-color | domterm hcat, sending html to the
   terminal to be rendered when displaying values.
 - Updated PR Review Process
   Recently, we have been fortunate to see a rise in submitted pull requests
   and we are super grateful for this growing desire to improve Nushell.
   Unfortunately, in some cases, a well-intended PR does not match the
   direction Nushell is going, forcing us to close it which leads to wasted
   time and effort. To help focus PRs in the future, we kindly ask potential
   contributors to first reach out to us before making a substantial change to
   Nushell, especially if the change will affect user experience. We updated
   our contributing guide as well as the PR template to reflect this policy.
 - Completion actions now more familiar (dandavison)
   We've also recently improved how completions work in Nushell to feel closer
   to how other shells work. Specifically:
    - Completion goes "as far as possible". So, the entire word if \ 
there's a
      unique completion, or else up to the shared prefix of possible
      completions.
    - Removes the quick completion behavior whereby a word was completed
      automatically as soon as the input came to have a unique completion.
    - Tab now completes instead of selecting the next menu item (this can be
      configured)
 - Breaking changes
    - New --force (-f) flag for the mv command. This change alters mv default
      behavior. By default overwriting existing files is now prevented (You can
      use alias mv = mv -f in you config to get the old defaults back). (#6904)
    - The column name for the command name in $nu.scope.commands has been
      changed from command to name. Thus, $nu.scope.commands | where name =~
      zip would give you specific command info. (#7007)
    - The str distance command now directly returns an Int instead of a record
      {"distance": <Int>} (#6963)
    - The argument order of format filesize was made consistent with other
      commands that accept a CellPath to specify fields that should be affected
      by it. Now the string specifying the format is the first positional
      argument and the cell path is specified in the following positional
      argument(s). (#6879)
    - The --perf flag for Nu was removed as part of an effort to simplify
      diagnostics logging #6834
