chore(upgrade): urfave/cli from v2 to v3 (#8035)

urfave/cli  v2 will eventually become unmaintained, switch over to v3 which is the latest supported version.

Note: the `docs` command would be a lot of work to restore with v3 ([the package is still in alpha](https://github.com/urfave/cli-docs)) An alternative to avoid a breaking change would be to not upgrade from v2 to v3 for that reason alone.
Note: these commits were cherry-picked from https://code.forgejo.org/forgefriends/forgefriends
Note: it is best reviewed side by side with no display of whitespace changes (there are a lot of those when converting vars to func).

- a few functional changes were necessary and are noted in context in the file changes tab
- https://cli.urfave.org/migrate-v2-to-v3/ upgrade instructions were followed in the most minimal way possible
- upgrade gof3 to v3.10.8 which includes and upgrade from urfave/cli  v2 to urfave/cli  v3
- upgrade gitlab.com/gitlab-org/api/client-go v0.129.0 because it is an indirect dependency of gof3 and requires a change because of a deprecated field that otherwise triggers a lint error but nothing else otherwise
- verified that the [script](https://codeberg.org/forgejo/docs/src/branch/next/scripts/cli-docs.sh) that generates the [CLI documentation](https://codeberg.org/forgejo/docs/src/branch/next/scripts/cli-docs.sh) still works. There are cosmetic differences and the **help** subcommand is no longer advertised (although it is still supported) but the `--help` option is advertised as expected so it is fine.
- end-to-end tests [passed](https://code.forgejo.org/forgejo/end-to-end/pulls/667) (they use the Forgejo CLI to some extent)
