Describe the bug?

When trying to build a new release tag (v*), the action does not select any previous commit and fails to report any changes.

To Reproduce

1. create workflow triggered on tag push:

on:
  push:
    tags:
      - v*

2. add and commit some dummy files, over a few commits
3. tag the latest commit as v1.0.0 and push the tag

What OS are you seeing the problem on?

ubuntu-latest or ubuntu-22.04

Expected behavior?

Changes detected correctly.

Relevant log output

changed-files
  Using local .git directory
  Running on a push event...
  Warning: No previous tag found
  Error: Unable to locate the commit sha: 
  Error: Please verify that the commit sha is correct, and increase the 'fetch_depth' input if needed
  Retrieving changes between  () → e6eb9203c6c2c87b4dad7177f06eddb6ad80e024 (v1.0.0)
  All Done!

Has all relevant logs been included?

• I've included all relevant logs

Anything else?

I've enabled fetch-depth: 0 for my checkout step, so it's not like the history is missing.
