Include capabilities to bump patch, minor and major for version.

[murilodag]

Hello @yanamura, is the ability to automatically bump patch, minor and major for the version something you are interested in having in this action?

@murilodag Thanks for your good question!

Currently this action is just using agvtool to bump version and build number. agvtool has ability to automatically update build number, but not version. To add ability to automatically bump version, we need to implement that feature by ourselves.

I think it's a good idea to add ability to bump version automatically.
