security: re-enable security scan release block

This was previously disabled due to an unresolved false-positive CVE.
Re-enabling both secrets and OSV + Go Modules scanning, which per our
current scan results should not be a blocker to future releases.

Also add security scans on PR and merge to protected branches to allow
proactive triage going forward.

See hashicorp/consul#19978 for similar change in that repo, adapted
here.
