Different link for specific galaxy instances of workflows and tutorials

The workflow and tutorial queries (https://training.galaxyproject.org/training-material/workflows/embed.html?query=microbiome) via the GTN are useful to filter for specific communities and are already used as iframes in subdomains such as https://singlecell.usegalaxy.eu/ and https://microgalaxy.usegalaxy.eu/:

The problem when using them in iframes for the subdomains is, that the links only point to the main instances i.e. usegalaxy.eu; this opens galaxy inside the iframe, it would be much more user-friendly if this could point to the actual instance i.e. https://microgalaxy.usegalaxy.eu/
