👷(CI) remove test-e2e-other-browser job

We don't maintain the test-e2e-other-browser job,
and it often fails due to various reasons.
To avoid unnecessary noise in our CI pipeline, we
will remove this job.

We are adding workflow_dispatch trigger to the e2e-tests
workflow, so that we can still run e2e tests on other
browsers when needed from the Github actions UI.
