Fix vscode settings generated by @yarnpkg/sdks

[brandonbothell]

What's the problem this PR addresses?

Adds VSCode version detection to @yarnpkg/sdks to ensure proper settings. See https://code.visualstudio.com/updates/v1_110#_unified-javascript-and-typescript-settings

Closes #7107

How did you fix it?

• I used the code --version command (or code.cmd --version on Windows) to check the version and parse it, just like we do for node in @yarnpkg/pnp.
• Then, if the version is compatible with the unified settings, use those and delete the old settings.
• If we can't figure out the VSCode version for some reason, we just add both sets of settings just to be sure it will work without modification.

Checklist

• I have read the Contributing Guide.

Edit: Release Strategy added; PR ready for review.

Original: I still need to check compatibility with Linux/macOS systems before converting this from a draft, at which point I will add a release strategy.
