justusbunsi f0d0c00ed6 Properly sanitize gitea admin output (#590)
### Description of the change

With https://github.com/go-gitea/gitea/pull/28390, Gitea 1.21.2 introduced warning log output within the result of `gitea admin <subcommand>` and therefore affects the current provisioning script.
That script previously assumed a clean result set and was therefore doomed to fail at _some_ point.

This introduces output sanitizing to trim such logs above the actual result table.

### Applicable issues

- fixes #589

### Additional information

The non-sanitized output were only an issue for admin account provisioning, and only when the username matched one of these words (in case of #589 it was `gitea`):
```text
.../setting/security.go:168:loadSecurityFrom() [W] Enabling Query API Auth tokens is not recommended. DISABLE_QUERY_AUTH_TOKEN will default to true in gitea 1.23 and will be removed in gitea 1.24.
```

LDAP and OAuth sources were not affected by this particular log line, but also processed non-sanitized result sets. Changing their code is a precaution.
