PSA: Use `extensions.experimental.affinity` to speed up extension

VSCode allows extensions to run in their own thread. This improves productivity, and also is more important as of recent PRs.

Add to settings.json:

"extensions.experimental.affinity": {
    "asvetliakov.vscode-neovim": 1
},

Next on my PR list is to make the extension automatically detect if this is set, and prompt if not.

You are correct, I did know that but didn’t think it was an issue. I didn’t think it would hurt to include both as they both benefit from this setting and then you don’t have duplicates in settings.json.

However, I can see how this can be confusing, and will delete that line when I have the chance.

Edit: I was referring to the README/psa snippet, I agree that when the plugin checks for this it should only add itself.
