Ontobee should not be "hard-coded" for the links, but either go to the right location or use PURLs

[kltm]

To reproduce:

• go to https://www.alliancegenome.org/gene/SGD:S000002812#function---go-annotations
• click a populated cell
• wait for table to populate
• go to evidence code in "Evidence" column
• the link will be to Ontobee, a la https://ontobee.org/ontology/ECO?iri=http://purl.obolibrary.org/obo/ECO_0000501

As we have been having Ontobee outages, and I can see this same information in AmiGO (and that's obviously under our control), I see no reason not to link to AmiGO with https://amigo.geneontology.org/amigo/term/ECO:0000501

@pgaudet I'm not sure of a priority for this, but I think it would be good to get to at some point.
First pointed out by @sierra-moxon , I believe in reaction to the linked AGE issues above.

Talking to @cmungall , if hard-coded, it should go to where the PURLs go; otherwise, get it recompiled.

Noting that ontobee is currently down again.
