[FEATURE] Update CI script (semantic-release)

[LBF38]

Is your feature request related to a problem? Please describe.

When pushing new commits or merging PRs in the main branch, the CI for new releases is triggered. Therefore, a new PR is created if a new release should be created.
This allows me to control the release and versioning while having an automatic semver bump.
However, if the PR or release branch already exists, the CI will fail and will not update the PR / release branch.

Describe the solution you'd like

The solution would be to update the script in the .releaserc file that controls the release behaviour. Therefore, I need to create a bash script, based on what is already written in the .releaserc file.

Describe alternatives you've considered

Deleting the release branch and associated PR, then re-run the job.
