replace jasmine with vitest

[dynst]

Unless Jasmine, Vitest doesn't need identical boilerplate files copied into every package directory.

Blocked on:
#1809 & #1832 & probably #1833

Converting is easy now that xit is in use:

• xit = it.skip
• jasmine.stringMatching = expect.stringMatching
• expect(a).withContext(b) = expect(a, b)
• expectAsync(p).toBeRejectedWithError(/regex/) = expect(p).rejects.toThrowError(/regex/)

[dynst]

Why is there a --stream argument that's always passed to all the tests? And why is it in the workflow config, instead of in the root-level package.json, or individual packages' scripts?

cosmjs/.github/workflows/test.yml

Line 103 in 8fb7421

run: yarn test --stream

cosmjs/.circleci/config.yml

Line 154 in 31db121

yarn test --stream

Is there another way to do whatever it is it's doing?
