💥 Regression Report

Updating git submodules stopped working in 2.2.0 due to the newly added target parameter. Submodules are updated by new commits, and so they fail the SemVer check (compared by hashes):

Steps to Reproduce

• Add a submodule in your repo
• Create a dependabot workflow to update submodules:

version: 2
updates:
  - package-ecosystem: "gitsubmodule"
    directory: "/"
    schedule:
      interval: "daily"

• Create a simple GitHub action for fastify/github-action-merge-dependabot

Expected Behavior

It should just ignore git submodules and automatically merge them regardless. A skip option for target would be a solution for that.
