fix(dev-infra): misc fixes for the compare master and patch script (#37150) 

This commit includes a couple minor fixes for the script that compares master and patch branch:
- take only relevant release commit into account while generating the diff
- fix the initial version display (avoid '+' sign from being added)
- removes obsolete parameter that was needed for v9.0.x branch only
