Bug #19295: Time#wday returns 7

This issue happens since Ruby 2.7, since Z and UTC are allowed for a zone.

[1] pry(main)> Time.new(2023, 1,3,0,0,0,"UTC").wday
=> 7
[2] pry(main)> Time.new(2023, 1,3,0,0,0,"Z").wday
=> 7

This also breaks all weekday Time#monday?, etc. methods.

• Is duplicate of Bug #19292: Time object's wday, yday, and isdst returns broken value (and so does to_a) when kwarg in: 'UTC' was given added

Seems same as #19291.

In #19292 it is said that 3.0 and 2.7 don't need while they do.

• Backport changed from 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN to 2.7: REQUIRED, 3.0: REQUIRED, 3.1: REQUIRED, 3.2: REQUIRED

The patch conflicted with 2.7, but could fix this issue by applying with preceding patches.
