DEV: Capture and log AR debug logs on GitHub actions for flaky tests (#25048)

Why this change?

We have been running into flaky tests which seems to be related to
AR transaction problems. However, we are not able to reproduce this
locally and do not have sufficient information on our builds now to
debug the problem.

What does this change do?

Noe the following changes only applies when `ENV["GITHUB_ACTIONS"]` is
present.

This change introduces an RSpec around hook when `capture_log: true` has
been set for a test. The responsibility of the hook is to capture the
ActiveRecord debug logs and print them out.
