Replace unclear fromStandardDate()

[MaxAake]

The Neo4j.Date functions fromStandardDate() and toStandardDate() are not inverse functions of each other, as fromStandardDate() takes the date that the StandardDate would correspond to in local time, and toStandardDate() creates a Date set at Midnight UTC.

This PR deprecates the old fromStandardDate() and replaces it with a drop-in replacement fromStandardDateLocal() which functions the same and fromStandardDateUTC() which takes the date as interpreted in UTC.

My brain was close to melting while trying to understand this PR 🫠

I think example code would go a long way. Something like this (maybe split the examples and spread them across the functions' docs)

// will do what it says on the tin
Neo4jDate.fromStandardDateLocal(new Date(2020, 01, 01))
Neo4jDate.fromStandardDateUTC(new Date(Date.UTC(2020, 01, 01)))

// Depending on the host's locale, might end up with a different calendar date
// than 2020-01-01
Neo4jDate.fromStandardDateLocal(new Date(Date.UTC(2020, 01, 01)))
Neo4jDate.fromStandardDateUTC(new Date(2020, 01, 01))

Optional: I think it might be very much worthwhile to run these tests for different time zones/locales. In particular the ones that are far off of UTC (and maybe also UTC itself).

Suggested change

	* fromStandardDateLocal(new Date("2010-10-10T00:00:00")) // This may cause issues as JS Dates are created at local time by default
	* fromStandardDateLocal(new Date("2010-10-10T00:00:00Z")) // Will create a date at 2010-10-10 as this date is created at UTC with the trailing "Z"
	* fromStandardDateUTC(new Date("2010-10-10T00:00:00")) // This may cause issues as JS Dates are created at local time by default
	* fromStandardDateUTC(new Date("2010-10-10T00:00:00Z")) // Will create a date at 2010-10-10 as this date is created at UTC with the trailing "Z"
