update linkML with external links

[only1chunts]

We have FAIRSharing records for all of the MIxS checklist. Is it possible to add links to those into our LinkML?
There may be an appropriate place holder in LinkML already for those sorts of things? But if not then I would suggest in the descriptions.
Change whats currently displayed on the front page to be:

Checklist	Description
MigsBa	Minimal Information about a Genome Sequence: cultured bacteria/archaea FairSharing
MigsEu	Minimal Information about a Genome Sequence: eukaryote FairSharing
MigsOrg	Minimal Information about a Genome Sequence: organelle FairSharing
MigsPl	Minimal Information about a Genome Sequence: plasmid FairSharing
MigsVi	Minimal Information about a Genome Sequence: virus FairSharing
Mimag	Minimum Information About a Metagenome-Assembled Genome FairSharing
MimarksC	Minimal Information about a Marker Sequence: specimen FairSharing
MimarksS	Minimal Information about a Marker Sequence: survey FairSharing
Mims	Minimum Information about a Metagenome or Environmental Sequence FairSharing
Misag	Minimum Information About a Single Amplified Genome FairSharing
Miuvig	Minimum Information About an Uncultivated Virus Genome FairSharing

Note also - The update to the textual description of the MIMS entry

Hi @only1chunts . Thanks for getting this down on paper.

I think I suggested assigning this to @sujaypatil96 because he is our LinkML documentation expert. But on further reflection, this linking shouldn't be added in the documentation generation phase, it should live in the schema itself, possibly as a mapping. Good news, @sujaypatil96 has been working on the rendering of mappings in docuemtation pages recently.

But we can also consider other LinkML slots to hold the relationship with FairSharing terms in the TWG meeting tomorrow (and assign somebody)

I would give this the "good first issue" label if we had that in this MIxS repo!

mappings have subtypes which adds some semantic clarity. Since the value of mapping relationship is a CURIes or URL, we assume the source is embedded in the value
