Add support for the cf.image field in fetch() properties

[jakubadamw]

Per the definition in https://github.com/cloudflare/workerd/blob/4fb4dbd88d30ff293267680d85a31ddef94fd9b6/types/defines/cf.d.ts#L171-L295.

This is based on the existing #233 authored by @seeekr, with some improvements and the completion of the set of properties supported.

@zebp any chance this could be reviewed? 🙂

Seems like there generally is a lot of outstanding PRs open and ready to be reviewed. I wonder what the best process of getting one's PR reviewed and merged is here? I think it would make sense to perhaps document the process in the README or, otherwise, external contributors may get discouraged from getting involved, seeing their contributions not picked up for review long after submission? (General observation, nothing personal!)

[zebp]

Some minor changes needed, but looks like it's on the right track.

And yeah I think you hit the nail on the head about the PRs, there's definitely more that should be done to make sure PRs don't stack up and get reviewed in a more timely manner. I like the suggestion of documenting a process for contribution, but I also will start to be more active in reviewing and dealing with issues. In the future please feel free to ping me directly, my Github inbox is a mess but any direct pings give me a notification on my phone that I do check.

@jakubadamw @zebp is there anything outstanding left for this change? I'm happy to pick it up and push it through as well if this one's too stale

[jakubadamw]

@b3ngg, @GodTamIt, I am sorry this was neglected for so long – busy times. I just pushed a new commit, addressing Zeb's feedback from Oct 2023 and bringing this up to date with the current state of the JS API.
