chore: move jest test to vitest

[yuming-long]

Summary

as suggested by speakeasy:

Also noticed that your installation of Jest in the SDK repo is causing an npm audit warning with 1 high severity vulnerability. If you're keen to switch then I highly recommend vitest. It's a mostly drop-in alternative and requires no config to work. We use it to test our SDKs.

Also found that its easy to add coverage report just by appending --coverage add the end of the make test commands, but tbd in the future

Test

ci should work as before
