shells/nushell: update to 0.70.0

Themes of this release:

 - New table flags
   --expand: changes a standard table view; expand the table structure so
   internally all data will be displayed as inner tables

 - NOTICE
   The expand mode can be considered generally slower than a base table view.
   So, if you have a large data set it may be slow.
    --expand-deep {int}: set a limit after which table enlargement is stopped
    --flatten: an --expand view option to return a set of values instead of
      table for a simple lists
    --flatten-separator {char}: a configuration of a separator for --flatten
    --collapse: changes a standard table view; expand the table structure in a
      squashed way

 - NOTICE
   collapse mode currently doesn't support width control, therefore if your
   terminal is not wide enough the table might be broken. The collapse mode can
   be considered generally slower than a base table view. So, if you have a
   large data set it may be slow.

 - Breaking changes
   The command first 1 now returns a list with the single value rather than the
   value itself. This brings it in line with the behaviour of last 1.
   The dataframe command with-sql or query dfr has been renamed to query df for
   consistency.

 - Next Steps
   We're continuing to work on language updates and hope to have more
   information for you soon.
