Add Linktree to social module (#2399)

Adds linktr.ee profile detection to the existing social module, alongside
LinkedIn / GitHub / Discord / etc. The username pattern is the
3-30 character window of [a-zA-Z0-9._] that Linktree uses on its
sign-up page.

Extends test_module_social.TestSocial with a Linktree fixture and
asserts both the canonical url and profile_name fields on the emitted
SOCIAL event.

Closes #2399
