Changes proposed in this Pull Request

Same code change as #1029: varwrap is typed with a ParamSpec, so the Variable methods that wrap an xarray.Dataset method (sel, isel, shift, rename, stack, ...) carry the wrapped method's parameters and return Variable for type checkers and IDEs, instead of an untyped Callable. See #1029 for the before/after screenshots and the notes on Pylance and ty.

On top of #1029:

• Merged current master.
• Release notes: moved the entry from the already-released 0.10.1 section to Features in the upcoming 1.0.0 section, and reworded it to say which methods are affected and what changes for users.

Closes #1029

Checklist
