Use InitWorkPathAndCfgProvider for environment-to-ini to avoid unnecessary checks (#25480)

Fix #25481

The `InitWorkPathAndCommonConfig` calls `LoadCommonSettings` which does
many checks like "current user is root or not".

Some commands like "environment-to-ini" shouldn't do such check, because
it might be run with "root" user at the moment (eg: the docker's setup
script)

ps: in the future, the docker's setup script should be improved to avoid
Gitea's command running with "root"
