[BUG] Changed files not working on self hosted runners

[pranav-paypay]

Is there an existing issue for this?

• I have searched the existing issues

Does this issue exist in the latest version?

• I'm using the latest release

Describe the bug?

Not working on self hosted github runners.

To Reproduce

1. Have a self hosted github runner.
2. Run this action as part of a workflow more than 2 times.

What OS are you seeing the problem on?

ubuntu-latest or ubuntu-20.04

Expected behavior?

Action should work on self hosted github runners.

Relevant log output

error: remote temp_changed_files already exists.

### Anything else?

This is most likely because the script adds a new origin to calculate the changed files.
In the self hosted runner, the state is maintained and the subsequent builds run into the issue of where the required git origin is already added.

I think a check can be added to see if this already exists.
