Internal review: version 8, stateful reconnect section of SignalR Config

Internal review: What's New: SignalR: Stateful reconnect

Fixes #30674

Added new section: Configure stateful reconnect

(I had to close an earlier PR of this #30829 and start over since I introduced some merge conflicts that were a bit too messy.)

Also updated per @BrennanConroy request (in previous closed version of this PR) to move the server example to the top example.
"I think this should be listed first. Server must allow stateful reconnect otherwise client settings are ignored.
We also don't need to put it for both clients, if it's at the top that should be obvious 😄"

@BrennanConroy, I closed the earlier PR for this and started over with this clean one to get through a merge conflict and a messed up branch.

Your requested change to move the server hub endpoint example up is in. I also cleaned up some repeated statements to make it a little more concise.

Does this look good?

@BrennanConroy,

• I added the server global and hub specific StatefulReconnectBufferSize examples.
• Cleaned up some very minor items in the doc.
• Updated the 8.0 What's New doc to mirror all changes and linked back to SingalR Config.

Hopefully, this all looks good. Thanks again for your help!

Looks good, feel free to not take the suggestions other than the typo fix.

You already link to the Configuration article -- you could omit the duplication of configuration details here, just announce the availability of SR and explain what it is, then rely on the link to the Configuration doc for the details about how to enable it. Just a thought.

Thanks! A good point. I considered not calling out the configuration options themselves and linking instead, but looking over the whole What's new doc, we tend to provide an example of the API or property that is new or changed. So I decided to keep with what that topic was already doing.
