Update @types/vscode and StatusBarItem implementation

[andyleejordan]

This requires updating the StatusBarItem implementation, but moreover,
raises the lowest supported version of VS Code.

Replaces #3174.

@rjmholt How do we usually handle raising the minimum supported version of VS Code itself? IIRC, you've said we generally just support the latest and latest - 1 versions, which means this update shouldn't be in the next stable release #3178, despite seeming small.

[rjmholt]

So I talked this through with @TylerLeonhardt (since he knows a fair amount about VSCode and its API) and we should use the minimum types version we support.

By not upgrading we trust VSCode not to make a breaking change in its latest API, but we can generally trust that.

[andyleejordan]

Perhaps there's a way to get Dependabot to ignore updates to @types/vscode (and so correspondingly vscode itself).

[TylerLeonhardt]

If you comment this in the dependabot PR, it will ignore it for the future. I thought I already did that for that dependency but maybe dependabot eventually forgets or maybe I forgot.

@dependabot ignore this dependency

[andyleejordan]

@TylerLeonhardt I just saw that lol, I'm really like dependabot so far!

[andyleejordan]

Converted to draft until the day we can update this.

VS Code is at 1.55.0 now, think we can revisit merging this? @rjmholt

[andyleejordan]

@rjmholt, I verified with @Charles-Gagnon that Azure Data Studio now supports at minimum 1.53.0, so we should be good to go now!
