Update stock-tracker extension - Fix yahoo finance rate limiting

[ericchernuka]

Description

• Fixes the stock tracker extension by adding user agent headers to mimic a browser so that it won't get rate limited.
• Fixes the throttle prop by providing a default true value as it wasn't adhering to the throttle previously
• Updates hotkeys from previous TODO's to support cmd+opt+up arrow and cmd+opt-down arrow when moving favorites

I haven't tried it out, but if adding the header helps with the Yahoo API issues, that's great 🎉
