feat(tests): move from karma to vite

[NefixEstrada]

This closes #1883

There are 3 tests that now fail. Other than the performance one, I'm not sure the others are ok, maybe they were already failing? They're marked with a TODO.
I wasn't able to run the tests using karma

Please, let me know if there's something that I'm missing!

This is a bit more than just replacing Karma, if I understand things correctly. This also replaces Mocha, Chai and Sinon with vitest?

That requires a bit more consideration if we want to replace all of those familiar components and become fully dependent on a single one.

[NefixEstrada]

Yes, this would change all the tecnologies to vitest. However:

• Mocha: the syntax is 100% supported, meaning no change for the developer
• Chai: the majority the syntax (assertions) is supported (and the unsupported ones change very little)

There's a comparison in the vitest docs: https://vitest.dev/guide/comparisons.html#mocha

Let me know if there's anything I can do!
