soft-✅ from me

TODO: merge this to main and update merge-main-5-16-1

• chore(deps): bump Microsoft.AspNetCore.Server.Kestrel.Core to 2.3.6 #4639

[jamescrosswell]

Ideally we'd avoid updating merge-main-5-16-1 from main again... it will mess with the changelog now that we have Unreleased changes in there.

I might cherry pick that Kestrel security fix instead of merging from main again...
