Support completion for new git switch and git restore commands

[kidonng]

Git 2.23 brings some new features which include two new commands: git switch and git restore, which are meant to eventually provide a better interface for git checkout.

Saw that yesterday. These are still experimental and the blog post does mention that these could change (names, parameters, etc) before shipping in final form. I'd be inclined to wait for the commands to be finalized before adding support for them in posh-git. But maybe @dahlbyk has a different take?

This feature was automatically enabled for me the last time I updated git. I don't have any experimental flags enabled or anything like that, so I think its mainstream at this point.

I've updated my local copy of the module to support this command, will you take a PR for the update?

@pinkfloydx33 Just show your fantastic work to the world☺️

[dahlbyk]

will you take a PR for the update?

Yes!

I don't know why github blog said experimental about this feature. Because no mentions about this in official changelog. It's look stable

@pinkfloydx33 Can you take a look at my PR (#702) and see how it compares to the changes you made to add support for these two commands.

How soon should it be available in PowerShell Gallery? Two extremely often-used commands are not live in half a year after implementation and in a month after release, is it Really OK? I see it's beta, but the current stable release without switch and restore is probably less usable than beta

The beta, which supports these two sub-commands, is in the PowerShell Gallery.
