fix(project-release): POST should not call Snuba (#69831)

Customer is hitting rate limiting when they shouldn't. ticket:
https://getsentry.atlassian.net/browse/OPS-5972
It turns out project release endpoint is intentionally skipping snuba on
POST requests but this call is ignoring the passed flag `no_snuba`.

More context on investigation:

I'm not familiar with release code so leaving it here to see if this is
the right behavior. Is it ok to set tag_values to empty at the time of
release creation?
