Use Punch tool for tracking and bumping project's version.

I'm not a fan of sticking this release stuff into the Makefile (it should be a shell script) nor is it good to run some random python scripts on every invocation of make, however, we already had that discussion previously on Slack -- if you're really going to fix this at some later time, then it's fine with me :)
Semantic versioning looks like a good choice 👍

Yeah, sticking all this into a Makefile is quite heavy 🙂. I agree we need to come up with something better in the future, preferably something that can be shared among repos (i.e. Oasis Core, Oasis Core Ledger).

If you mean the Punch tool, then this has been improved and it is only called when running the changelog Make target to bump the version appropriately.

however, we already had that discussion previously on Slack -- if you're really going to fix this at some later time, then it's fine with me :)

I won't mind if someone else also takes a stab at trying to improve our tooling 🙂.
