add support for versions to `port bump`

[lhaeger (Lothar Haeger)]

I regularly check my ports with port livecheck, which tells me which newer port versions could be built. Then manually edit the port file to update the version number, then run port bump before trying an install and start fixing things, if necessary.

Would be nice if I could skip the manual editing and directly tell port bump the new version number, so it not only updates the hashes but the version string as well. If I wanted to prepare an update for my-port from version 1.0 to 1.1, I could then run port bump my-port@1.1.

Of course port bump would need to understand all alternative ways to set a port's version e.g. github.setup .

And then automatically generate a PR and run tests builds on the CI system, like homebrew's bot does.

then you just have to hit "commit" if you like it.
