EZSP v11 (EZSP PROTOCOL VERSION 11) support in bellows?

[Hedda]

FYI, read that some people in the community noticed that the EZSP protocol version has been incremented to EZSP v11 in Gecko SDK v4.2 / Zigbee EmberZNet v7.2 and that EZSP v11 () was not mentioned in the latest UG100 (EZSP Reference Guide) documentation from Silicon Labs which SiLabs only updated for EZSP v9 and state that no additions were added between EmberZNet PRO Release 7.1.1 and 7.2.2:

https://github.com/SiliconLabs/gecko_sdk/blob/gsdk_4.2/protocol/zigbee/app/util/ezsp/ezsp-protocol.h#L33

Mention under miscellaneous changes in release Zigbee EmberZNet SDK 7.2.2.0 GA (Gecko SDK Suite 4.2 March 8, 2023):

"Updated the ezspPollHandler function with updated input arguments, that required updating the EZSP_PROTOCOL_VERSION to 0x0B"

0x0B hexadecimal = 11 in decimal.
