[SECONDARY FEATURE] Professor Search Hotkey

### User Story

As a student, I want to be able to quickly search professor information with a hotkey instead of clicks.

### Technical Tasks

- Create a hotkey that when activated, autofocuses the search input on the extension window
- Use [this documentation](https://developer.chrome.com/docs/extensions/reference/api/commands) as a starting point
- Settings panel has hotkey toggle and documentation on what the hotkey is mapped to

### Acceptance Criteria

- Entering the hotkey opens the extension window and autofocuses on the input
- The hotkey should be able to be activated anywhere.
- There should be an option in settings to disable the hotkey
