[Feature] Enable modification of the prompt in the UI

[ryan-at-kettle]

This is a development tool and should be written in a way that exposes all options to the user, rather than simplifying those options.

Allowing customization of the prompt and any logic associated with the prompt for each run would enable a greater depth of review:

• Allows for additional contextual information to be provided on the codebase: language version, standards, etc
• Allows for a faster feedback process with prompts, furthering the speed of the development of this tool
• Allows requesting additional information with the review

I added a very similar functionality to summarize.site https://github.com/clmnin/summarize.site/pull/5 (which actually inspired me for doing this extension).

If you decide to build this, there's this https://developer.chrome.com/docs/extensions/mv3/options/

  "options_ui": {
    "page": "options.html",
    "open_in_tab": false
  },

Or just ChatGPT it. Little known secret is that ChatGPT did all of the initial code for this extension 😅
