Display lineage ancestry below lineage name

[flaneuse]

With all the evolution within Omicron, and especially all the recombinants, I'm finding it hard to keep track of what particular lineages are, for instance: "what is CJ.1?".

For tiny label below BQ.1, we could add a little piece of text, like:
BQ.1 <- BA.5.3 <- B.1.1.529 (Omicron)

For a recombinant, we could maybe do something like:
XF <- B.1.617.2* x BA.1*

These could also hyperlink to the ancestor's page. Depending on the page, I could see this being best placed as a small annotation and/or tooltip to provide context about what each of these lineages actually are.

note: i thought for awhile about making those maps a bit more graphical to show more of the tree structure, but i think they're probably 1) a decent amount of trouble to generate; 2) doesn't add a ton of new info. but open to exploring!
