[NET-6969] security: Re-enable Go Module + secrets security scans for release branches (#19978)

* 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.

* security: run security scans on main and release branches
