Add scripts for bumping major versions and creating aliases

[azeey]

Used to automate the creation of #3288. I'm not sure if we should put the scripts in a separate directory or elsewhere entirely.

I used about 10 lines of bash to create the aliases in #3285 (see PR description). Does that seem adequate, or do you prefer the scripts in this PR?

Reviewing both of the approaches seems different to me: the code in #3285 is generating the collection aliases, gz-jetty-foo and the code in this PR is generating the next version by scanning existing formulas and add +1. It would be good if we can unify both. I can try to give this a shoot.

Note: gz-launch is missing here, probably intended, are we expect to remove it in Gazebo Kura?

I've produced some code that unifies both features in a single documented python script. #3355
