Previously in multi-threaded app servers, such as Puma, the Rails time
zone configuration setting was not being respected. Rails expects the
time zone to be set in `application.rb`, and the default value is set in
the `active_support.initialize_time_zone` Railtie. However, since we
load this setting from a config file, the time zone for GitLab is set
inside an initializer.

Setting `Time.zone` in the initializer worked fine with Unicorn, but it
stopped working with Puma. All responses would return timestamps in UTC,
irrespective of the system or Rails time zone. This happened because
`Time.zone` calls `Thread.current`. Since the time zone wasn't set for
the thread, Puma would default to `Time.zone_default`, which was UTC.

We now set the default and the Rails configuration settings to be
consistent.

Make Issue Analytics singular

Closes #235797

See merge request gitlab-org/gitlab!39506

Originally we called the feature Issues Analytics. The plural form
felt a bit awkward. We recently introduced Merge Request Analytics,
where the singular form felt more natural and also conflicted with
Issues Analytics. So this re-names Issues Analytics (plural) as
Issue Analytics (singular).

Document new transaction metrics

The test was previously failing because it was possible for a note to be
deleted before the browser rendered the page, so there was note to
reply.  We fix this by deleting the note only after the page has been
displayed and the user has clicked the reply button.
