Add SD-JWT-VC to Ecosystem Compatibility section

[brentzundel]

per https://lists.w3.org/Archives/Member/w3c-archive/2025Apr/0606.html

§5.11 Ecosystem Compatibility should explicitly list SD-JWT and SD-JWT-VC
to paragraph 1 which lists digital credential formats that do not natively
use the VCDM. SD-JWT-VC even explicitly specifies it does not use the VCDM
v1.0, v1.1, or v2.0. As SD-JWT(-VC) is a popular VC format for eIDAS it
should be explicitly stated like the others.

Brent Zundel: comment source.

Brent Zundel: For each of these comments, I will provide text and link to source of comment.

See github issue vc-data-model#1593.

Brent Zundel: comment on VCDM, text suggests say we list SD-JWT-VC to the ecosystem compatibility section. The suggested response will be that we plan to address comment in future version of specification.

Ivan Herman: Any response we make is better to send via email.

Brent Zundel: I will do that.

Kevin Dean: Is there something we can add to the response to provide reasoning? Out of scope for current scope of work?

Brent Zundel: This is an editorial change, we can address it under our current charter, seeing how ideally we shouldn't change text of REC, we can address this later.

Michael Jones: That's fine.
