[GSOC 24] - Automated release notes generator and packaging script fixes

[omkar-334]

Hello Mentors,
I have opened this issue to share the Getting Started tasks and receive feedback.
Github link - https://github.com/omkar-334/Synfig-Changelog-Generator
Also, which is preferred - tracking the local repo or the main branch from Github? I've included both in the tasks.
I've used the libraries GitPython and PyGithub respectively.

Should I now work on grouping the commits based on the Conventional Commit types (feat, fix, build, docs, etc) ?

Thank you,
Omkar
