Audit missing Serverless content

[bmorelli25]

Audit content to determine what's missing from Serverless. For #4127.

Here's a spreadsheet we can use to identify commits that should have been ported to serverless but weren't: audit serverless/stateful content (internal only). Each @elastic/obs-docs writer should review the commits they authored and confirm if the commit should be ported, if it was it ported, and link to the port PR.

Check off your name when you've reviewed all your commits in the spreadsheet:

• @alaudazzi
• @bmorelli25
• @colleenmcginnis
• @dedemorton
• @eedugon (I know you don't have any yet, but I didn't want to leave you out!)
• @mdbirnstiehl

Bonus points:

• If a PR should not be ported describe why in the "Notes" column.
• Review some commits authored by non-@elastic/obs-docs contributors.

@bmorelli25 can we close this ticket?

The last time I updated the Google sheet was September 26, but we merged the new PR template on September 23. If the team feels good about how we've been using the PR template, then I think we can close this. If not, let me know if you want me to run the script again to get all commits since September 26.
