Gitea service panics when attempting to clone/pull

[eeyrjmr]

Description

upon upgrading to gitea-1.22.3 (from 1.22.2) on windows, any clone/pull via git results in a 500 error. The WebUI "mostly" still functions but does slow down.
Closer examination of the logs shows a panic

2024/10/29 10:34:07 ...rs/common/errpage.go:26:RenderPanicErrorPage() [E] PANIC: runtime error: invalid memory address or nil pointer dereference

since this was a MINOR bump, the service was "downgraded" to 1.22.2.
gitea-1.22.3-windows-4.0-amd64.exe and gitea-1.22.3-gogit-windows-4.0-amd64.exe were both tried and both exhibit the same issue

Regression of Don't init singing keys if oauth2 provider disabled (#32177)

[eeyrjmr]

I can confirm that Oauth is disabled.
This was done for an odd issue and I meant to raise a PR on that but I honestly forgot

The issue was a RESTRICTED user would have a js overlay about Oauth if it was enabled. This might have been fixed so I can recheck and if it is still an issue open a separate PR
