Failing to push refs after tag is created

Nobody has claimed this yet.

Hi,
I'm creating a workflow that creates a new tag, generates release notes, and pushes it to the main branch. The tagging job works as expected, but when I'm trying to push the code to the branch after the tag, I'm getting:
`error: src refspec refs/heads/main matches more than one`

Here's the action.yaml file:

```yaml
name: CI
on:
push:
branches:
- main

permissions:
contents: write
jobs:
release:
runs-on: [ self-hosted ]
permissions:
contents: write
steps:
- uses: actions/checkout@v2
- name: Bump version
id: tag_version
uses: mathieudutour/tag-action@v6.0
with:
github_token: ${{ secrets.PUSH_TOKEN }}
default_bump: minor

- name: "✏️ Generate release changelog"
uses: heinrichreimer/github-changelog-generator-action@v2.3
with:
token: ${{ secrets.PUSH_TOKEN }}
output: CHANGELOG.md
headerLabel: "# 📑 Changelog"
breakingLabel: '### 💥 Breaking'
enhancementLabel: '### 🚀 Enhancements'
bugsLabel: '### 🐛 Bug fixes'
stripGeneratorNotice: true
issues: false
issuesWoLabels: false
pullRequests: true
prWoLabels: true
author: true
verbose: true
sinceTag: v2.25.0
- name: Commit CHANGELOG Changes
run: |
git config user.name "GitHub Actions"
git config user.email noreply@github.com
git add CHANGELOG.md
git commit -m 'Update Changelog.'
git remote set-url origin https://x-access-token:${{ secrets.GITHUB_TOKEN }}@github.com/${{ github.repository }}
git push
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```

Any idea why I cannot push new changes after the tag is created or how it should be done to work properly?

Start with action.yaml and the git push step after mathieudutour/tag-action@v6.0; inspect the refs after tag creation and reproduce the `src refspec refs/heads/main matches more than one` error. Done means the workflow commits CHANGELOG.md and pushes to main without the refspec error.
