Is your feature request related to a problem? Please describe.

I'm using self-hosted runners on a machine with Ubuntu 18.04. The default git version is 2.17. When using this action I kept seeing the following errors:

Error: Unable to locate the current sha: ...
Error: You seem to be missing 'fetch-depth: 0' or 'fetch-depth: 2'. See https://github.com/tj-actions/changed-files#usage
Error: Process completed with exit code 1.

I tried 'fetch-depth: 0' and 'fetch-depth: 2' and was still getting the same error. Tuns out git version 2.17 doesn't have the command git rev-parse (https://github.com/tj-actions/changed-files/blob/main/diff-sha.sh#L35). Updating git to the latest version fixed the problem.

Describe the solution you'd like?

Two things come to mind:

• Specify the minimum required git version in the README
• Check that the git version is above the minimum and raise a better error message if it's not
