feature: Customisable commiter variable

[centrumek]

Hello!

I want to have an option to provide extra env vars for this action:

• committer_name
• committer_email

I can be a volunteer, if maintainers agree on this feat :)

@omBratteng can I implement this feature :)?

Go ahead 😄

Hi @omBratteng I've created a PR -> #377, you can review and release if it is okey :D
