Update gitea to 1.9.4

This is the latest release from upstream. We're not
currently running with any additional patches, although
we did submit one for the atomic updating of repo counts. That
patch will be in 1.10.

There is only one change to the templates we've customized
since the ref we're running from. That is included in the
repo/header.tmpl.
