Read time_zone.name instead of time_zone

[pravi]

Description

Without adding time_zone.name, the returned value is considered invalid by tzdata.

Closes: #2249

Not that simple, will try a different fix.

This looks like a bug in gitlab now, as https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/initializers/time_zone.rb?ref_type=heads sets

Rails.application.config.time_zone = Time.zone

puts Time.zone
(GMT+00:00) UTC

Which is not a valid identifier.
