Update connectivity-architecture-overview.md

[azarboon]

Connection pooling has been barely discussed in the documentation of SQL Managed Instance. Given the authority of this documentation, I've elaborated it to inform readers about the nuances.

@azarboon thank you for this very nicely written treatment of pooling!

I think it should be kicked up a floor and appear in shared SQL MI & SQL DB docs. Client-side pooling applies to both, after all :)
(Also it's not AAD any more, today we should call it Entra ID).

@MashaMSFT can you work your magic to move this article to the "shared concepts" space between SQL MI and SQL DB?
Thank you!

@zoran-rilak-msft thanks for suggestions. I've edited them. I couldn't get right the relative path to that ADO article so I added full URL. You should be able to edit the file by yourself (I enabled it). Kindly please sign it off as you deem appropriate.

Thanks @azarboon !

@MashaMSFT - I think the right address should be /dotnet/framework/data/adonet/sql-server-connection-pooling?
Also, let's see if this paragraph should go in the shared MI & DB section.

Thanks @zoran-rilak-msft
