Timothy Flynn 462e7b0c87 LibJS: Introduce Time Zone Identifier Parse Records to Temporal
This is an editorial change in the Temporal proposal. See:
https://github.com/tc39/proposal-temporal/commit/96bb9b0

Note that we already had a struct for this, but now that it has a proper
name and spec link, this renames it to match other Parse Records and
places it alongside them.
