Allow on the fly toggling of configs

[andyearnshaw]

Clear and concise description of the problem

I work in a large monorepo, in excess of over 100 projects. Sometimes I'm working in different areas an need to be able to quickly reconfigure the Vitest plugin to run tests for the current area I'm working on. Editing the workspace file is cumbersome and having too many enabled at once is noisy.

Suggested solution

The Playwright plugin detects all the configs in the workspace and allows you to toggle them in a really convenient manner:

It would be great if the Vitest plugin could implement an identical method of activating configs.
