Nice script, also take a look at my one @jv-k/bump-version.sh.
I'm here because I just got this link generated by GitHub Copilot while writing a my own ./version.sh script for a python project.
Here is my script: https://gist.github.com/kaar/dc5514218fc5ecfdb608a32cfe021eb7

Thank you!
A question, out of curiosity: Why did you decide to make the default bump up MINOR instead of PATCH? (I’ve found the latter more practical, to do MINOR and MAJOR bumps manually.)
