Wrong example in readme "Manually triggered debug"

[maratori]

Due to the bug in github actions need to change example in readme how to manually trigger debug

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      # Enable tmate debugging of manually-triggered workflows if the input option was provided
      - name: Setup tmate session
        uses: mxschmitt/action-tmate@v3
        if: ${{ github.event_name == 'workflow_dispatch' && inputs.debug_enabled }}
