Internal release: Add UI to capture feedback

Context

As a part of the internal MVC release of &17781, add a piece of UI that will allow users to leave feedback for the new file tree browser.

Design proposal

  • Add a Provide feedback button to the bottom of the file tree browser panel
  • Button must link to the feedback issue: #581271
  • Please open the feedback issue in a new tab, so users don't lose context of their repository.
