How should we convey more variety in team links?

Initially brought up here: https://github.com/ember-learn/ember-website/pull/1027/files#r1205627030

I'm thinking since twitter is maybe a bit of a dumpster fire, we should think about supporting alternative means of linking to folks' socials?

For example, i'd prefer to link to my linktree, rather than twitter: https://linktr.ee/nullvoxpopuli

We can use one of those chainmail link icons for generic links?
