Prefix option for --git-tag flag

[EdenEast]

--git-tag option will create a commit and tag with the version as the tag and message. There is no way to prefix this message. For example adding 'v' to the beginning of the commit message, tag message and tag name. This would also align with npm version and yarn version commands. The prefix might be a requirement for a version tag.

Propose a --prefix option. This option will be applied if the option --git-tag is also passed. It will prefix:

• git commit message
• tag commit message
• tag name

That would be relly nice
