microGalaxy lab workflow URLs

A few issues with workflows in [5_workflows.yml](https://github.com/galaxyproject/galaxy_codex/blob/main/communities/microgalaxy/lab/sections/5_workflows.yml):

- Some links like https://workflowhub.eu/workflows/1189?version=2 which is OK (maybe omit the `version` param to default to latest?)
- Then some like https://dev.workflowhub.eu/workflows/... - is dev subdomain a mistake?
- Then some like https://usegalaxy.eu/published/workflow?id=61fe08fb3d5e83f8 - is it possible to have these linked to workflowhub instead or are these only available on EU?

For WFHub links, we decided that URLs like this make for the best user experience:
`{{ galaxy_base_url }}/workflows/trs_import?trs_server=workflowhub.eu&run_form=true&trs_id=1189`

This opens the TRS import function in the current Galaxy server, so the user can import the workflow immediately. We also include a `view_link` button so they can also view on workflowhub if they wish:
