Create a GitHub action to generate Changelog with gitmoji-changelog

[frinyvonnick]

It could be nice if users could add an action that generate a changelog in their CD pipeline.

@frinyvonnick Shall I take this up.

Hi @Joel-hanson 👋

Thank you for considering to make a contribution to gitmoji-changelog 🙏

Sure, it is free to take. Don't hesitate to ask if you need some help.

@frinyvonnick I created an action that does this for my own sanity:

https://github.com/marketplace/actions/gitmoji-changelog-action

Feel free to copy/fork it if you want.

it just runs npx gitmoji-changelog and commits the code with a gitmoji commit message.

In my use case I use this action everytime there is a push to the main branch to always keep the CHANGELOG.md up to date.
