Bug: Unable to retrieve commits history when using Squash and Merge on Pull requests

Nobody has claimed this yet.

This is the action I used in my workflow file:

```
- name: Bump version and push tag
id: tag_version
uses: mathieudutour/github-tag-action@v6.1
with:
github_token: ${{ secrets.GITHUB_TOKEN }}
default_bump: false
create_annotated_tag: true
```

This is a sample PR commit that is squashed and merged from my `dev` branch into the `main` branch:

```text
feat(api): add historical query (#40)
* feat(api): add historical query in api (#50)

Co-authored-by: =person_1 <=person_1@live.com>

* fix(api): remove buggy api

* refractor(api): change data structure

* build: update query dashboard

---------

Co-authored-by: =person_1 <=person_1@live.com>

* test: add new integration tests (#45)

The following integration tests are added:
1. test 1
2. test 2

The following changes are made:
1. Rename integration test test script name
2. Solve bugs in function A
3. Solve bugs in function B

* build(tests): add pytest in requirements.txt (#48)

* build: update dashboard (#49)

* fix(api):dashboard query -history features

* fix: test script

* refractor(api): change data structure of response

* fix: test script

* fix: api logic

* build: update dashboard

Co-authored-by: person_1 <123456789+person_1@users.noreply.github.com>
Co-authored-by: =person_1 <=person_1@apecia.com>
Co-authored-by: person_2 <123456789+person_2@users.noreply.github.com>
```

This is the logs I get from my workflow run:

```

So far I've squashed and merged two PR's from the `dev` branch to my `main` branch and both of the PR's do not create any tag or release.

I've checked my `main` branch commits history and there are more than 60 commits but the logs always shows `Analysis of 0 commits complete: no release`.

Start with the workflow configuration and the action run logs shown in the issue, then trace how github-tag-action determines the commits to analyze after a squash-and-merge. Reproduce the reported history with the provided settings and verify that the action analyzes the merged changes and creates the expected tag or release.
