make editing profile page accessible

fixes CNVS-13993

Things were not being labeled correctly. They are now.

Test Plan

Given you've enabled profiles for your account
And you're using a screen reader
When you go to the profile page
And you edit the profile page
And you edit the "Bio" text
Then the bio text area should be labeled
And when you add or edit a link
Then the links title label should be read
And the links url should be read
