Add information about the workflow status

[deliaBlue]

After opening an issue to test whether or not the workflow meets the criteria to be on the "Standardized usage" and passing the tests in the GitHub actions, the user is left alone with no more information about its workflow status.

To avoid this uncertainty, it would be great to add the following information:

1. The schedule/policy to check the different workflows in the catalog and include them (if they meet the criteria) in the "Standardized usage" section.
2. A timestamp to tell when the last run was triggered. This will prevent the user from keep refactoring the workflow (when it is already in a good condition) following the logs in the Snakemake workflow catalog.
3. Whether there is, or not, a way to manually trigger a re-run of the pipeline for a specific workflow.

I totally agree, all good ideas!
