fix(build): Revert unintended Replay tsconfig changes

[Lms24]

This PR reverts a few changes I unintentionally comitted and merged in #6288. It caused build errors which for some reasons did not our CI's "build" step to fail but caused size-check fails in https://github.com/getsentry/sentry-javascript/actions/runs/3546454900
