[aaxelb]

Purpose

better support open, semantic, friendly web standards and common practices

fixes #10102

Changes

set rel="nofollow me" on user profile links

rel="me" so these links can be used to verify osf account ownership by services such as mastodon, and rel="nofollow" because we don't know anything about the links by default, so we can't actively endorse them
