ENVIRONEMNT_ID does not include branch name

[pixelass]

Reading through the source code the ENVIRONMENT_ID should include the branch name.

source: https://github.com/contentful/contentful-action/blob/main/index.js#L44-L66

Expected Behavior:

GH-my-branch-name

Actual Behavior:

GH-merge

Context

workflow/action

      - uses: contentful/contentful-action@v1
        env:
          SPACE_ID: ${{ secrets.SPACE_ID }}
          MANAGEMENT_API_KEY: ${{ secrets.MANAGEMENT_API_KEY }}

I also looked through https://github.com/contentful-labs/contentful-action-example but found no hints to faulty usage from our side.
