Before this PR is merged, you can use ts-snapshots-plugin instead of typescript-snapshots-plugin to support vitest.

I tried doing that, but it doesn't work - maybe I'm doing something wrong?

• I installed ts-snapshots-plugin (npm i -D ts-snapshots-plugin)
• I updated my tsconfig.json: "plugins": [{ "name": "ts-snapshots-plugin", "snapshotFileFlavor": "vitest" }],
• I restarted VSCode

I still can't see the previews or go to snapshot files.
