Update collaboration.md

[toddewilliams]

I updated the CodeTogether description to include some enhancements that we just shipped in CodeTogether 4.2. I also added a bit more detail to the feature list and provided some hyperlinks in a couple of places where people would likely appreciate more detail.

I made no changes to the other sections.

Fixes #4280

Thank you so much for sending these changes over.

Much appreciated ✨

Glad to contribute! But the build seems to have failed. Anything for me to do here?

Is it possible for you to run yarn fmt locally? Otherwise, if you checked the box "allow edits from maintainers" then I can do it for you. Just let me know!

[toddewilliams]

Fortunately, I did check the box to allow edits from maintainers because it's your project and that only seems right.

So I'd greatly appreciate it if you'd do the needful to push this on through Joe. My days of being in git every day are behind me at this point. Thanks in advance!

Awesome! (No way for me to know sadly without asking)

Let me see if I can push changes to get this fixed
