Invalid timezones showing up in timezone lists

View of the admin panel ui dropdown list where you can set the timezones for a new user

View of the sqlite db table for timezones

I believe that the db is missing some of the timezones that the browser can evidently see. Seems like there's a difference in behavior in the output of that function call between nodejs 18.19.0 and firefox 123.0.1 on mac sonoma 14.4.

IMO UTC and whatever others are there should probably be supported as an option; however, the easier thing to do would probably be to make this line a call to the api instead of initializing from the browser: https://github.com/mitre/tir/blob/main/components/UserAdmin.vue#L451
