feat: rename id to recommendationId

[mmiermans]

Goal

Be more consistent with naming between Glean and the API.

I'd love feedback/perspectives on:

Is this naming better? The plan is to also apply the renaming to the MoSo content feed API.

Deployment steps

• Sync with Chutten to check that this attribute is not yet used in Nightly. It doesn't look like the Firefox change is reviewed yet.

Seems this change is timely, given a comment from @ScottDowne yesterday:

It is my understanding that we can at some point migrate away from id: item.tileId,, and just use recommendation_id: item.id,? Is that correct? Otherwise, I think it's kinda confusing to have all these different ids with names that are not super descriptive.

Looks good to me. Do we want to make sure chutten has had a chance to respond before merging?
