Update name for 'Elasticsearch Service'

[kilfoyle]

According to the last naming update I've seen, Elasticsearch Service is now Elastic Cloud Hosted.

The {{ess}} attribute has been carried over into the migrated docs, so I think it makes sense to continue using this attribute with the new name.

CC @eedugon, @kosabogi, @shainaraskas since I know you've been working on what were the Cloud docs.

lgtm. we might want to add another one that matches the new acronym (ech) for ease of use for contributors as well but can do that separately

[shainaraskas]

actually, sorry. thinking for one more second about this. we can't do this because ESS used to have only one meaning, but now it's represented by two concepts - Elastic Cloud and Elastic Cloud Hosted

I suggest that we add a new dedicated variable and start using it instead to avoid confusion

@shainaraskas Okay. I've added a new variable instead. I guess the existing "ESS" attributes will need to be reviewed or replaced en masse.

+1 with adding a new variable and "deprecating" the old one. {{ess}} will need to be replaced by either {{ecloud}} or the new {{ech}} in the sources. I think the content refinement we're doing now as part of the migration is a good opportunity to do that accurately.

With the recent addition of serverless, it might even be wise to check that existing {{ecloud}} occurrences are correct and aren't just meant to designate {{ech}}

Nice to have this as an option now!
