Bug: Check for updates via menu-bar sub-menu action (macOS)

- OS: macOS
- Version of IPFS Desktop [0.20.0]

**Describe the bug**
Using latest version of ipfs-desktop, manually selecting to check for updates locks up the UI when the desktop application is not open.

**To Reproduce**
Steps to reproduce the behavior(macos):
1. Start ipfs-desktop
2. Ensure the menu-bar application is visible, and then close the ipfs-desktop window (the application will still be running, and accessible via the menu-icon)
3. Click the ipfs-desktop menu-bar icon
4. Hover over about
5. Click on 'Check for updates'
* The sub-menu may close (I believe this is only on the newest version). If it does, re-open it before the update-checking is done in order to reproduce the bug.
7. Notice that the UI for the menu-bar ipfs menu locks up

The ipfs-desktop application will re-open in the dock with a pop-up confirmation indicating that you are on the latest version.

**Expected behavior**
Checking for updates is a non-blocking background operation.

**Screenshots**
Action:

Locked up UI:

Latest version confirmation popup:

**Additional context**
When I first ran into this bug, the Dock did not display the ifps-desktop icon. So I was unable to close the confirmation popup, and the UI stayed locked up, with the menu-bar menu remaining open and inaccessible.
