shells/nushell: update to 0.83.1

Nushell 0.83.1 (hot-fix)

A few days ago, we released the 0.83 version of Nushell. As you can see in the
release notes, the release included a major upgrade to the type system as well
as wide-reaching breaking changes.

Extensive efforts were made before the release to mitigate these changes to
make them easier to adopt when 0.93 was released, and included:
 - quite a lot of command signatures have been updated to keep functionalities
   at the same level while adding better type checking
 - major integration scripts from 3rd-party applications have been fixed prior
   to the release

However, as you might have noticed and thanks to the feedback of you the
community, more issues and bugs have been found. Many commands needed additional
updates to play well with the updated type system. We decided to release a
hotfix release to address what had been found, and this is that release.
You can find out more about the hotfix in Tracking issue for 0.83.0 fixup #9812

What does the hot-fix release address?

Most of the type-system-related issues have been fixed, hopefully bringing most
of the command set of Nushell back to its previous feature level with the nice
addition of better input/output type checking and annotations. In a few places,
the type system itself was fixed, as with the case of $rest args now
type-checking correctly in a pipeline.

What will the hot-fix release NOT address?
Bring the let-env command back to life.

Thankfully, the community helped by updating their Nushell integrations and
releasing corresponding new versions.
Please, check your tools like starship for updates.
Fully fix the dataframe integration.

When upgrading the type system for the 0.83, we removed a semi-working system
that enabled the dataframe commands to run both in a lazy and eager mode, but
only if the types were known at parse-time. Due to the complexity of reworking
this and the dataframe support currently being a tier-two feature in Nushell,
we won't be able to fully fix this with this patch release. Thankfully @ayax79
started work in #9858 which promises to make the dataframe commands work again
within the general Nushell type system.

Breaking changes for plugin authors

With the type system changes in 0.83.0 any plugins that declared that their
signature "vectorizes_over_list": true were not able to automatically \ 
broadcast
their operation for a type T (e.g. number) over a list<T> input. With this \ 
patch
release, we removed this field from nu-protocol.

You need to add the list<T> signature if necessary. Also recompile your
plugins using nu-plugin 0.83.1 or remove the vectorizes_over_list field from
the signature information if you don't use nu-plugin (e.g. plugins not
implemented in Rust).

Breaking changes for plugin users

You may need to recompile or update your plugins and then re-register your
plugins.
