Support older Move language versions

[ferencdg]

Hi, our have to stay with Move 1.0 as we are also compiling to older chains that doesn't support Move 2.0. If I use this extension, I get tons of very intrusive suggestions that can only be applied if we upgraded to Move 2.0. Would it be possible to add a language version selector?

[ferencdg]

can you guys at least document what are the diagnostic messages that can be turned off? I had to clone your repo and go through a bunch of rust code until I found the names:

[mkurnikov]

You can see the name at the diagnostic popup in the editor, as a aptos-language-server(DIAGNOSTIC_CODE_TO_DISABLE) (replace-with-method-call here)

Same thing with hover.

As for different versions of the Move language - we'll discuss it, we could at least document a set of Move 2.0-specific (at soon Move 2.2) diagnostics to disable.

UPD.
Codes for the suggestions are also documented in https://github.com/aptos-labs/move-vscode-extension/blob/main/docs/quickfixes.md
