Added the set of ETSI SAREF technical specification.

This is needed for the ongoing W3C SSN specwork.

The Smart Applications REFerence (SAREF) suite of ontologies is published as a set of open standards produced by ETSI TC SmartM2M. Some references to recent technical specifications were missing or outdated.

In general, the ETSI references are mostly outdated and it would be worth re-generating file etsi.json

@tidoust are you managing merges (or is it August in France :-) ?)

Yes, see #846, ETSI entries have not been updated for some time already.

The PR changes all lines in etsi.json. I suspect that's probably the result of some re-formatting. Would it be possible to restrict the updates to the actual updates to ease review?

[maximelefrancois86]

my bad. I added CRLF line endings.
It's all in order now.

I note that all but two entries in the etsi.json file use an http scheme instead of https, whereas HTTP requests to www.etsi.org seem to always return a permanent redirect to the HTTPS URL. It would be great to use https URLs throughout. That's orthogonal to this update though.

A mere 2024 works for a human readable date, but 2024-01 does not. rawDate should be used instead:

Suggested change

	"date": "2024-01"
	"rawDate": "2024-01"

See inline for required change to fix validation against schema.
