feat: add fail_on_error parameter support on github actions

[subashcs]

Description

The current GitHub Actions fail if commitlint throws an error.

This pull request adds a new boolean parameter, fail_on_error, to GitHub Actions. This parameter will determine whether to fail the CI or proceed to the next step when commitlint throws an error. The default value for this parameter will be true.

The fail_on_error parameter is set to false when the user wants to ignore the commit message validation or handle the error in their own way.
