Release tools: Update list of bug fixes tool for 4.4 Beta/4.5 Alpha

With the transition from 4.4 Alpha to 4.4 Beta and 4.5 Alpha, a few
small changes could be made to the "list of bug fixes per release" tool
to make it more reliable:
- 4.5 is added to the list so it can detect reports made from
Blender 4.5.
- Update the example usage to of the script to be the exact arguments
triagers should use for 4.4 Beta and 4.5 Alpha so triagers just need to
copy and paste the arguments to the command line.

With 4.4 Beta and 4.5 Alpha, small updates to the "list of bug fixes
per release" tool could be made to make the script.
