Uses "jest-setup-glob" to simplify testing

[kettanaito]

With the addition of jest-setup-glob dependency we can remove the following commands:

• yarn test:internal
• yarn test:integration
• yarn test:integration:node
• yarn test:integration:browser

And use a single yarn test command that will use a proper environment setup based on the given test filename.

Something is terribly wrong with this CI build: random dependencies start to fail as if not being installed.

We're not using Jest anymore and it's fairly easy to do glob-based environment matching with Vitest.
