Job Runner works with its own copy of repo

I have a stage in .gitlab-ci.yaml aimed to increase my python project version.

version_up_for_dev:
  only:
    - development
  stage: Bump Version
  script:
    - poetry version prepatch
    - PROJECT_VERSION=$(poetry version | awk '{ print $2 }')
    - git commit -m "[CICD] bump version for Development to $PROJECT_VERSION" pyproject.toml
    - git tag -a v$PROJECT_VERSION -m "[CICD] version $PROJECT_VERSION"
    - git push --atomic origin HEAD:${CI_COMMIT_REF_NAME} v$PROJECT_VERSION -o ci.skip

After one run tag was created inside the runner version of a remote repository, but git push command failed. Consequently, in the origin repository there no tag v$PROJECT_VERSION, but now each time CICD pipeline is triggered runner sees tag v$PROJECT_VERSION inside it version of the repo, so it’s impossible to successfully execute command git tag -a v$PROJECT_VERSION since the tag already exists.
When I run git log --graph --decorate --oneline --all inside runner container I can see that tagging is presented in the history.

But there no such commits in remote repo!

What’s the correct way to do tagging and additional commits inside runners?

I’m using GitLab Community Edition [13.7.6].
