[chore] updates code.superseriousbusiness.org/oauth2/v4 to ssb-v4.5.3-1 (#4245)

A brief note on the above change: Go does not seem to like version tagging outside of `v?[0-9\.]` formatting, so it translates `ssb-v4.5.3-1` to `v4.5.4-0.20250606121655-9d54ef189d42` and as such sees it as a "downgrade" compared to the previous `v4.9.0`. which functionally isn't a problem, everything still behaves as it should, but it means people can't just run `go get repo@latest` for this particular dependency.
