Create manual action for creating a bump version PR

[dzikowski]

Plus fix this job by passing correct script: https://github.com/hyperledger-labs/fablo/actions/runs/17642333753/job/50132079109 which has wrong file name here: https://github.com/hyperledger-labs/fablo/blob/main/.github/workflows/release-on-tag.yml#L54

The job should be manual, so it's easy to call it when needed. It should accept as a parameter the version parameter, as in the script: https://github.com/hyperledger-labs/fablo/blob/main/bump-version.sh. Valid input should be also set 1.2.3.
