SQL: ODBC: document newest connection string parameters (#44185)

* SQL: ODBC: document newest conn string parameters

This commit adds the documentation for two newly added connection string
parameters: AutoEscapePVA and IndexIncludeFrozen.

It also removes the recommended OSes from the prerequisites list and
places the recommendation distinctively: the unmet prerequisites will
fail the installation, while the driver would install on other OSes than
those recommended.

* address review suggestions.

- adjust phrasing for clearer message.
