[Feature] Add shortcut keys to theme dev

Do you suffer from long logs? Do you accidentally close your browser window and have to scroll all the way up in your terminal to find the theme dev links? Look no further than the addition of shortcut keys!

Feedback before official PR

Are there any issues with the way I implemented the shortcut keys / listener
I added documentation for each shortcut using the renderLinks method but I don't particularly like the way it looks. EX: The render in the terminal normally looks like Customize your theme at the theme editor but is now Customize your theme at the theme editor - shortcut key "e"
Any general feedback on this is welcome

WHY are these changes introduced?

Fixes https://github.com/Shopify/cli/issues/4713

With the amount of logs theme dev generates, it can be difficult to find the original store links such as previewing your theme, or opening the theme editor. Having shortcut keys is a simple way to open the links without needing to physically click on them in the terminal.

WHAT is this pull request doing?

Add shortcut keys to the theme dev command We look for keypresses, specifically: t - opens the theme locally e - opens the theme editor p - opens the share preview we also look for ctrl + c to exit the process

How to test your changes?

Pull down the branch Build the branch Run the theme dev command Try out the shortcut keys. Click some links, save some files, and see that it does not affect anything else running, ctrl+c out to confirm you can exit the same as before.
