Support TypeScript 4.9 `satisfies` operator

[karlhorky]

Hi @daidodo 👋 Hope that you are well!

Is your feature request related to a problem? Please describe.

It would be great to be able to use the TypeScript 4.9 satisfies operator!

However, currently, format-imports identifies this as an unused import:

import {AType} from '../a.js'; // 💥 This will be removed as an "unused import"

const a = 'abc' satisfies AType;

Describe the solution you'd like

The import of the type should not be marked as unused.

Describe alternatives you've considered

Ignore all type imports using keepUnused

Additional context

I'm using VS Code 1.73.1 which has TS 4.8.4 built in, but I'm using 4.9.3 via my node_modules:

One thing I could imagine is that the format-import VS Code extension needs a newer version of VS Code to get full TS 4.9 support... 🤔 Is this how it works?

Thanks for the feedback!

You are probably right that the fix would be updating the built-in TS.

This should be fixed in 7.5.2.

Nice, it works for me, thanks! 🙌 Closing.

I guess it was mostly this commit?
