No TypeScript errors on improper use of dateTime.with

[kavsingh]

When passing a plain date time to dateTime.with (zoned and plain dateTime) there are runtime errors thrown, but no TypeScript errors are raised. The runtime exceptions seem to be expected as per current docs and are fixed by using .withPlainTime

typescript	4.1.2
proposal-temporal	0.6.0

This change was fairly recent, we disallowed the use of timeZone (in case of ZonedDateTime) and calendar (in case of both Plain and Zoned) in the with method. Would you like to make a PR to fix the types?

This no longer applies to this repo. Polyfills should decide this for themselves.
