Setting baseline path in gihub actions

How do I use the `--baseline-path` flag in github actions.

Is it possible to set the path in my config file `.gitleak-config.toml`. I can't see a reference to in the [gitleaks configuration file](https://github.com/zricethezav/gitleaks#configuration) docs or the [default configuration file](https://github.com/gitleaks/gitleaks/blob/master/config/gitleaks.toml)

Read the linked Gitleaks configuration documentation and the default config/gitleaks.toml file, then trace how the --baseline-path flag is supplied in GitHub Actions. Clarify whether the path can be set through .gitleak-config.toml or only through the action configuration, and document a working example.
