Duplicated mapping key

[exostin]

Expected Behavior

Code for github actions workflow works correctly when using "Repositories" plugin

Current Behavior

Currently, on the stable branch, when using "Repositories" plugin, "Action code" tab on https://metrics.lecoq.io/ generates a code that tries to set two values to one key by default.

plugin_repositories: 100
plugin_repositories: yes

which results in an error message
The workflow is not valid. .github/workflows/main.yml (Line: x, Col: y): 'plugin_repositories' is already defined
x, y - depends on your workflow code

Possible Solution

The issue can be fixed by removing one of the lines I mentioned earlier.

Context (Environment)

I used https://metrics.lecoq.io/ to generate an action for my GitHub Readme, this was the result:

# Visit https://github.com/lowlighter/metrics/blob/master/action.yml for full reference
name: Metrics
on:
  # Schedule updates (each hour)
  schedule: [{cron: "0 * * * *"}]
  # Lines below let you run workflow manually and on each commit
  workflow_dispatch:
  push: {branches: ["master", "main"]}
jobs:
  github-metrics:
    runs-on: ubuntu-latest
    steps:
      - uses: lowlighter/metrics@latest
        with:
          # Your GitHub token
