GitHub Action fails for pre-January 2024 Morea sites

[philipmjohnson]

If you have an existing pre-2024 Morea site and try to build it after January, 2024, you will find that your GitHub action fails due to changes at GitHub.

To fix this, you must do the following:

1. Update your .github/workflows/main.yml file to be the same as the current one:

• https://github.com/morea-framework/morea/blob/main/.github/workflows/main.yml

2. In your browser:

• Go to your morea repo in GitHub,
• Click "Settings"
• Select "Pages" from the left side menu
• Under "Build and Deployment", select "Github Actions"

Now you should be able to rebuild your site without problems.
