Project and organization links have inconsistent anchor underlining

[mcbouslog]

Expected behavior

In the External Project Links section on a project home page and Links section on an organization home page hover or focus on the anchor tags will have consistent underlining.

Current behavior

Icons appear inconsistently underlined (from https://www.zooniverse.org/organizations/meredithspalmer/snapshot-safari):

If in ExternalLinksBlock.jsx the following is added:

i::before {
  display: inline-block;
}

after the current icon styling it appears to consistently remove an underline, but feels a bit hacky.

Per the organization landing refactor (#5554), this issue is no longer relevant, though edits to organization links section are still needed, as noted in #5592.
