🚀 Feature Proposal

Add two new configuration properties dependabotAuthor and dependabotCommitter that allows users to configure https://github.com/fastify/github-action-merge-dependabot/blob/main/src/getDependabotDetails.js#L2-L4 and set custom values

note : I am open to sending a PR about this

I run dependabot-core (the core framework behind dependabot) privatel yand my user details are not what the actions expect

Example Configuration

dependabotAuthor:
   required: false
   default: "dependabot[bot]"
dependabotCommitter:
   required: false
   default: "GitHub"

Example Input

dependabotAuthor : myUser
