tzTokenizeDate: Remove weird unneeded regex

[TheThing]

According to my tests, format will never display unicode characters. I ran through every single list of timezones in wikipedia (https://en.wikipedia.org/wiki/List_of_tz_database_time_zones) and not a single time did it ever produce a weird non-ascii output. In fact, putting all possible dtf.format(date) in a set and comparing it with:

var s = new Set()
/* run through every timezone and do s.add(dtf.format(d)) */
s.forEach(x => console.log(x, x === x.replace(/\u200e/g, '')))

Produced exactly the output you would expect:

10/24/2023, 24:00:00 true
10/24/2023, 03:00:00 true
10/24/2023, 01:00:00 true
10/24/2023, 02:00:00 true
10/23/2023, 15:00:00 true

10/23/2023, 17:00:00 true
10/23/2023, 22:00:00 true
10/23/2023, 21:30:00 true
10/24/2023, 11:00:00 true

10/24/2023, 10:00:00 true
10/24/2023, 05:00:00 true
10/24/2023, 13:00:00 true
10/24/2023, 06:00:00 true
10/24/2023, 12:00:00 true

10/24/2023, 05:30:00 true
10/24/2023, 09:00:00 true
10/24/2023, 04:30:00 true
10/24/2023, 05:45:00 true
10/24/2023, 06:30:00 true
10/24/2023, 03:30:00 true
10/23/2023, 23:00:00 true
10/24/2023, 10:30:00 true
10/24/2023, 09:30:00 true
10/24/2023, 08:45:00 true
10/24/2023, 13:45:00 true
10/23/2023, 14:00:00 true
10/24/2023, 14:00:00 true
10/23/2023, 14:30:00 true
10/23/2023, 13:00:00 true

There is no reason to run unecessary regex on ascii strings.

That's great. Thank you for verifying this so thoroughly @TheThing.
