Helm chart for dashboard not pushed to repository

[Labiote]

We have seen that the chart repository of OCM does not have the dashboard chart. Modifications need to be made for it to work:

• Probably change the chart name from ocm-dashboard to dashboard (since the repository is name dashboard and the way you prepare and push packages use the repository's name, not the chart's name)

      shell: bash
      run: |
        set -e

        # Read repositories.json and properly escape for GitHub Actions
        repositories_json=$(cat ${{ inputs.repoRoot }}/.github/repositories.json | jq -c .) # You build the matrix here based on what is in the repositories.json which is a dictionnary with repo's name
        echo "repositories=$repositories_json" >> $GITHUB_OUTPUT

        # Extract repository names for matrix
        repository_names=$(echo "$repositories_json" | jq -r 'keys')
        matrix_json=$(echo "$repository_names" | jq -c '{"repository": .}')
        echo "matrix=$matrix_json" >> $GITHUB_OUTPUT

• Add the information in the repositories.json since the dashboard repo is missing from it
