Temporal.TimeZone.prototype.equals: Missing call to ToTemporalTimeZoneSlotValue

[anba]

Step 3:

Return ? TimeZoneEquals(timeZone, other).

But other first needs to be converted to a time-zone value through ToTemporalTimeZoneSlotValue.

Another good find. This was introduced in adbdbf1d meaning it's actually part of the Time Zone Canonicalization proposal, which, since the July TC39 meeting, now lives inside the Temporal proposal.

I think we should just fix it since it seems pretty clear what the intention was, but I'll punt it over to proposal-canonical-tz for now since I'm not actually a champion of that proposal.

(For some reason I cannot transfer it, so I'll copy it manually.)
