Current tab shortcuts reuse reserved MacOS shortcuts

Before submitting a bug report

• [X] I updated to the latest version of Multi-Account Container and tested if I can reproduce the issue
• [X] I searched for existing reports to see if it hasn't already been reported

Step to reproduce

1. Try opening a Container with Keyboard Shortcut 3 or 4 (Shift-Command-3/4).

Actual behavior

A screenshot is being taken, because Shift-Command-3 and Shift-Command-4 are reserved for screenshots.

Expected behavior

The wanted Container should open.

As a workaround, you can change the default shortcuts for Multi-Account Containers by following the instructions in https://support.mozilla.org/en-US/kb/manage-extension-shortcuts-firefox.
