Fixed action failure when the .distignore file is not present in repo.

[iamdharmesh]

Description of the Change

As reported in #136, the action(version 2.2.1) fails when the .distignore file is not present in the repo.

This issue was introduced in #130. #130 added support for including build files in SVN when the action is used without a BUILD_DIR and .distignore file. In order to achieve this, the git commit command was added without checking if there were any untracked files to add and commit. Running git commit on a clean working tree results in a failure with the message (nothing to commit, working tree clean).

This PR fixes the issue by adding a condition for untracked files check and only running git commit if untracked files are present.

Closes #136

How to test the Change

1. Fork "Eight Day Week"
2. Update the deploy plugin workflow to use action from this fix branch and update workflow to run in a dry-run
3. Create a new release on repo. (It will trigger the deploy action)
4. Verify the deploy action, it should run successfully without any failure.

The test I have done on the sample repo: https://github.com/iamdharmesh/GlotPress/actions/runs/6109282764/job/16579976180
