Updated Enforce-CRLF action to v1.2.1

[DecimalTurn]

A recent action run for Enforce-CRLF failed and I'm trying to see why. My suspicion is that it's related to the it-auto-commit-action version updated in https://github.com/DecimalTurn/Enforce-CRLF/releases/tag/v1.2.1

Comparision between v1.1.3 and v1.2.1

Hopefully, this fixes it. Otherwise, I'll investigate further.

The workflow running from this PR won't have the permission to perform the commit, but the reason for the failure earlier is not related to permission.

The earlier failure has to do with the fact that the latest commit on the branch was not the one the Enforce-CRLF action was running on because the documentation update created a new commit on the branch before Enforce-CRLF was able to do its job.

I've added an option to run the Enforce-CRLF action on demand (workflow_dispatch), so it can be eaisly re-run in case the documentation update causes it to fail.
