DDSSEC13 — Wrong value of RTPS Minor version in 7.4.6.1

Section 7.4.6.1 "Change to the RTPS minor version number" says:

Implementations of this specification shall set the RTPS protocol version number present in the RTPS Header. The RTPS Major version number shall be set to 2 and the RTPS Minor version number shall be set to 3. Future revisions of the DDS-RTPS specification shall take this fact into consideration.

This was copied and pasted from DDS Security 1.1. It is wrong because when DDS Security 1.2 was released the current RTPS version was 2.5.

We should find a better way to keep the RTPS Minor version updated. the difference between the standard version and the protocol version is confusing. perhaps there is not as much need to update it since the different specifications already reserve ranges for discovery PIDs.
