Open "Get Help" on default browser

**Describe the usability problem**
Under the hamburger icon, Get Help currently opens in-app. This makes it very difficult for a user to submit the required information (address, txid, state logs, etc.) as they have to close the form to gather each.

**Expected behavior**
Ideally, when clicking Get Help, the support site will open on the user's default browser, so they can easily switch between apps to copy/paste address, txid, and to download/upload their state logs when needed.

Start at the hamburger menu's Get Help action and trace how it currently opens the support site in-app. Change the action so the support site opens in the user's default browser, then verify that users can switch apps and copy or upload the required information.
