frontmatter job in on_gpml_change is not using latest GPML

[AlexanderPico]

To reproduce:

1. Edit title in WP1.gpml
2. Commit/push to trigger workflow

Obs:

• the info.json is updated to match the GPML
• the .md file is updated to match the prior commit and does not match the latest GPML or info.json.

Do we need to insert another "pull hack" here: https://github.com/wikipathways/wikipathways-database/blob/main/.github/workflows/on_gpml_change.yml#L176? Like we did here: https://github.com/wikipathways/wikipathways-database/blob/main/.github/workflows/on_gpml_change.yml#L316?

Feels like we're doing something wrong, systematically. We shouldn't need any of these "pull hacks," right?

I think I found others with the same issue! Will try these solutions.
actions/checkout#439

Oddly enough, I think this fixed the issue. We had to specify fetch-depth and ref like so:

    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 0
          ref: main

In all subsequent checkouts within a workflow (when following a commit job). This forces the job to pull the latest rather than the same revision that was pulled at the start of the workflow.

I've updated all our ymls to use this pattern and I removed the cd/pull/cd hack. And my test edit of WP1 passed!
