[GHSA-9hxg-w7qf-hh93] Use Go pseudo-version for fixed version

[cookesan]

This updates the fixed version for gogs.io/gogs in GHSA-9hxg-w7qf-hh93 from the Gogs application version 0.11.82.1218 to the Go module pseudo-version for the referenced fix commit.

Evidence:

• The advisory references gogs/gogs@ff93d9dbda5cebe90d86e4b7dfb2c6b8642970ce.
• That commit is pkg/tool: improve SanitizePath (#5558) and updates APP_VER to 0.11.82.1218.
• go list -m -json gogs.io/gogs@ff93d9dbda5cebe90d86e4b7dfb2c6b8642970ce resolves it as v0.11.80-0.20181218063808-ff93d9dbda5c.
• The Advisory Database convention for Go ranges omits the leading v, so this PR records 0.11.80-0.20181218063808-ff93d9dbda5c.

This addresses one item from #7355. I kept the PR to one advisory per the contribution guidelines.

Friendly follow-up on this advisory improvement. The intent here is only to record the fixed version for gogs.io/gogs as the Go module pseudo-version for ff93d9dbda5c, since that is the identifier dependency tooling resolves for the referenced fix commit. If that matches current advisory-database conventions, this should be ready for review; if not, I'm happy to adjust it.
