ChangeLog: corrections and minor cleanup of 23.10 release

When released the YANG status section claimed IPv4/IPv6 MTU was
not-supported, which was very confusing since the following Changes
section clearly states added support for it.

The YANG Status section was wrong.  It has also been cleaned up a bit.
E.g., no need to mention which native model provides an augment or a
deviation, to an end-user the only thing that matters is what is added
to or removed from the standard models.

[skip ci] becuase none of this warrants a rebuild.

+	 - User login shell, default: `/bin/false`
+	 - State information for remotely querying firmware version information
+   - **deviations:**
+     - timezone-name, using IANA timezones instead of plain string
+	 - UTC offset, only support per-hour offsets with [tzdata][]
+	 - Usernames, clarifying Linux restrictions
+     - Unsupported features marked as deviations, e.g. RADIUS
    - [infix-system-software][]: firmware upgrade with `install-bundle` RPC
-   - [infix-system][]: timezone-name deviation, using with IANA timezones,

  - [ietf-interfaces][]:
-   - [infix-interfaces][]: deviation for `if:phys-address` to allow read-write
-   - [ietf-ip][]: augmented with IPv4LL similar to standardized IPv6LL
-   - [infix-ip][]: deviations (`not-supported`) added for IPv4 and IPv6:
+   - deviation to allow read-write `if:phys-address` for custom MAC address
+   - [ietf-ip][]: augments
+     - IPv4LL similar to standardized IPv6LL
