[Bug 244025] www/gitea: Update to 1.11.0 (fixes security vulnerabilities)

Update port to Gitea 1.9.5. This release fixes six security issues, a large number of bugs, and adds a large number of features. Release notes:Patch forthcoming, but there is an issue with the simple upgrade to the new version that I need to investigate first. At least the web interface appears to be broken.
