REPLAY-528 Add docs

[jas-kas]

This platform-redirect link is missing so many platforms, for example, all of the JS frameworks have their own Privacy page (e.g., Angular) - I'm not sure why that is :/

[sfanahata]

I'll look into it. Probably start a different PR to fix that page.

[sfanahata]

So, I did some digging, and the reason why it's not rendering all the JS frameworks is because they all are proxied from the one common privacy page under JS. Because of that, it's tricky to have all of them listed on the /platform-redirect/?next=/session-replay/privacy/ page. I reformatted the platform redirect pages to pull in all the JS frameworks in the list, so they should now all show up across any /platform-redirect/ page.

I also found that there was insufficient logic to pull in Dart because it was nested under guide, and we were only checking for top level platforms. Both use cases will now be fixed. PR: #14914

[jas-kas]

I've asked @Jesse-Box to help with a new image asset for the Replay Details page so we can show off the AI summary. Using the Sentry colour palette for this would be nice, and so it can be consistent with the other visuals in the Replay product docs

Demo Replay: https://demo.sentry.io/explore/replays/6b47b0f25c0843dcaf737c055458d0f7/?project=580[…]lore%2Freplays%2F&statsPeriod=30d&t_main=ai&yAxis=count%28%29`

Let's also update the second image on this page

Edit: @michellewzhang can help out here on visuals! 😄

assets have been updated here: https://www.figma.com/design/NNLgAJyzZno8NrBuJPVFQi/Assets--Product-Docs-v2--Copy-?node-id=3401-71&t=GxLKZGqTmNJDGh7V-0 (i had to create a copy of the original file since i didn't have edit access). all replay images have been updated in this pr (excluding mobile images, since we are hiding ai tab on mobile replays for now).

[jas-kas]

@michellewzhang assets look great! ✨

still seeing the old images on the latest vercel preview https://sentry-docs-ewbq8pkob.sentry.dev/product/explore/session-replay/web/ despite your update 🤔 , not sure why

[coolguyzone]

Big lift, looks good! 🏄‍♂️

[jas-kas]

<3 latest changes look good, thanks @sfanahata!

[sfanahata]

@jas-kas and @michellewzhang - I've updated with all the suggestions, except updating the privacy page, which I'll take on in a different PR shortly. LMK if there's anything more I can help with here. I'll keep this one hanging out until we're ready to release the feature.
