Deno Support

[lishaduck]

Clear and concise description of the problem

I use Deno (sometimes) and I also use Vitest (sometimes). As of very recently, I can use them both. However, the vscode extension still uses Node.js to invoke Vitest, so the vitest cli crashes, and the while extension detects tests, they're all grey and won't run.

I'd be more than willing to test a PR. I'd also be willing to write one, but I don't foresee having the time to write one any time soon, so don't expect anything tomorrow 🙃

Suggested solution

Detect if there's a deno.json file (or, perhaps, read the deno.enabled vscode setting?), and run deno run ./node_modules/vitest instead of node run ./node_modules/vitest (the tricky thing is that deno doesn't have a node_modules folder by default, but requiring one seems reasonable to me).

Alternative

Don't officially support Deno.

Additional context

I usually have chose between Vitest and Deno, but, given the status of denoland/deno#23882, I was trying it out. It works great! (except for coverage, which should be fixed in the next Deno release)
