Version Bump for git using Fish Shell

Intro

One feature that I really like from npm is the version command which handles bumping either patch, minor, or major version number following the [Semantic Versioning] standards. This sets the version attribute in your package.json file and creates a [git tag] using the new version number.

For example you can run the npm version minor command from the root of an npm project and it will change the version from 1.2.12 to 1.3.0 write this out to your package.json file and create a git tag for the new version.

Since the vast majority of my projects are php projects and not npm, I don't get a chance to use this feature nearly as much as I would like, so I found myself wishing there was a way to do this directly from git.
