Use self-hosted Renovate with self-hosted Forgejo

I host current Forgejo version with the corresponding runner in Docker on Windows. Forgejo is exposed to Windows as localhost:3000. In Forgejo, the repository URL is http://localhost:3000/repo/repo.git. Now I want to test Renovate self-hosted with this repository, so I run a Forgejo job with this config:

jobs:
  renovate:
    runs-on: docker
    container:
      image: node:20
      options: --network forgejo_default
    steps:
      - name: Checkout
        uses: actions/checkout@v4.3.0

      - name: Install Renovate
        run: npm install -g renovate

      - name: Run Renovate
        env:
          LOG_LEVEL: debug
          RENOVATE_TOKEN: ${{ secrets.FORGEJO_TOKEN }}
          RENOVATE_PLATFORM: gitea
          RENOVATE_ENDPOINT: http://host.docker.internal:3000/api/v1/
          RENOVATE_AUTODISCOVER: "true"
          RENOVATE_AUTODISCOVER_FILTER: "repo/*"
          RENOVATE_HOST_RULES: '[{"matchHost":"localhost","hostType":"gitea","url":"http://host.docker.internal:3000"}]'
        run: renovate

It does not matter what I try, it always fails because the local repository URL is localhost and it fails with:

DEBUG: Git function thrown (repository=org/repo)
       "err": {
         "task": {
           "commands": [
             "ls-remote",
             "--heads",
             "http://**redacted**@localhost:3000/repo/repo.git"
           ],
           "format": "utf-8",
           "parser": "[function]"
         },
         "message": "fatal: unable to access 'http://localhost:3000/repo/repo.git/': Failed to connect to localhost port 3000 after 0 ms: Couldn't connect to server\n"

Is there any way to make Renovate overwrite localhost to e.g. Forgejo or something that is accessible from within the renovate container?

Found the (obvious and simple answer) myself... I added an entry on local hosts file to point localhost to forgejo. Now it´s working!
