Previously, `HistoricalData.date` was a `date`. When doing date range
calculations such as `HistoricalData.where(
Date.parse('2020-10-20')..Date.parse('2020-10-23'))`, any records
containing 20th or 23rd are included in the result.

However, with `HistoricalData.date` as a timestamp with time zone,
20th would be included (since the time component is assumed to be 00:00)
but 23rd would be excluded.

In order to include both days, we need to use
`.beginning_of_day` and `.end_of_day`. Both methods are time zone aware
and will use the `Time.zone` if available.

Set the time and timezone of existing data to 12:00 in Time.zone since
the sidekiq-cron gem evaluates crons in the Rails timezones.

Fix Merge Request "Edit in Web IDE" dropdown link on MR diffs page

See merge request gitlab-org/gitlab!45653

As seen in QA pipelines and discussed in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/42229, the Grape
API initialization would fail if the database were empty. We now check
the existence of the `features` table to prevent this from happening.

This still does not allow us to change the feature flag dynamically, but
it unblocks the test failures.

Upgrade to Ruby v2.7.2

See merge request gitlab-org/gitlab!44223

Since Ruby 2.7.2 comes with bundler v2.1.4 by default, we need to
upgrade the Gemfile.lock and bump the CI cache keys. We also need to
install bundler v1.17.3 to ensure a smooth transition for other
dependencies, like Gitaly.

Exclude development gems from QA bundle install since debaser doesn't
compile on Ruby 2.7.
