ci: Skip optional E2E tests on release branches (#14424)

Optional tests should not block releases.

There are two groups of optional tests:
1. Canary type tests
2. Tests that send data to sentry

IMHO both of these can be skipped on release branches, as failure in
either of them should not affect the release. They will (for now) still
run on develop, we can revisit this if we want.
