Improve resolution process for nonfatal setup issues

Summary:
  - When a setup issue is nonfatal (i.e., a warning), instruct the user to edit the value from the web UI instead of using `bin/config`.
  - When the user edits configuration in response to a setup issue, send them back to the issue when they're done.
  - When an issue relates to PHP configuration, link to the PHP documentation on configuration.
  - Add new-style setup check for timezone issues.

Test Plan: Mucked with my timezone config, resolved the issues I created.
