fix(replay): update replay doc to show how to redact urls

[fasyy612]

Changes

Please describe.

Add screenshots or screen recordings for visual / UI-focused changes.
We should emphasize that we can already do url redacting for replays on our docs, it's a useful privacy feature.

Checklist

• I've read the docs and/or content style guides.
• Words are spelled using American English
• Use relative URLs for internal links
• I've checked the pages added or changed in the Vercel preview build
• If I moved a page, I added a redirect in vercel.json
