8.0: Feature tracking SignalR: October

[wadepickett]

This issue is tracking all 8.0 related features that must be accounted for in the SignalR docs from preview to post RTW to make sure we don't miss anything.

This issue description will be continuously updated and will move between monthly sprints as we go.

After each doc is updated, update the What's new in ASP.NET Core 8.0 doc with links. This must be done fast since many folks are in that file, checked out no longer than 2 hours.

Note: Future update but not this sprint for July 2023:
Once this feature has config finished, Update SignalR configuration topic to show how to enable and disable Seamless reconnect. Given this feature is in early support phase in preview 5 and 6 and no configuration exists for it as of 7/17/23, I will wait to update this topic for this feature once configuration is in place in a later preview or the GA.
