Use Temporal for time stamps

[remcohaszing]

Is your feature request related to a problem? Please describe.
YAML 1.1 defines the !!timestamp tag. This is a way to define date-time values. Currently these are parsed into Date objects. The problem is that YAML timestamps hold time zone information, but the Date object does not. This is a broader problem in the JavaScript ecosystem. It was fixed by the addition of Temporal.ZonedDateTime.

Describe the solution you'd like
I think it would be nice if YAML timestamps are parsed into Temporal.ZonedDateTime instead of Date.

Describe alternatives you've considered
N/A

Additional context
At the moment of writing, Temporal still has very limited availability. It might not be worthwhile to add this until at least all supported versions of Node.js support it.

Yeah, this seems like soemthing to return to closer to v3's final release, to consider then whether Temporal is well enough supported. Once it's available on Node.js, it's not clear to me if it'll be backported to older versions, and our current minimum is 20.19.

Unflagged Temporal support will land in Node.js 26 thanks to the update of V8 to 14.6 , but is unlikely to be backported to older versions.
