Doc Text .The `Extended Master Secret` TLS Extension is now enforced on FIPS-enabled systems

With this update, the TLS `Extended Master Secret` extension (EMS - RFC7627) extension is mandatory for TLS 1.2 connections on FIPS enabled RHEL 9.2 systems. This is in accordance with the upcoming FIPS-140-3 requirements. TLS 1.3 is not affected.

Legacy clients that do not support EMS or TLS 1.3 now cannot connect to FIPS servers running on RHEL 9.2. Similarly, RHEL 9.2 clients in FIPS mode cannot connect to servers that only support TLS 1.2 without EMS. This in practice means that these clients cannot connect to servers on RHEL 6, RHEL 7 and non-RHEL legacy operating systems. This is because the legacy 1.0.x versions of OpenSSL do not support EMS or TLS 1.3.
