Adds an e2e test for real time updates of issue assignees

In the following MRs:

1. https://gitlab.com/gitlab-org/gitlab/-/merge_requests/35292
1. https://gitlab.com/gitlab-org/gitlab/-/merge_requests/33176

We broke support support for these previous version by introducing
features that are only available in 6.4+ and 6.2+
https://gitlab.com/gitlab-org/gitlab/-/issues/271218 .

The simplest option here seems to just be to document that it's
unsupported rather than trying to fix these since we're going to remove
support soon anyway for all of `6.x`.

The upgrade to Ruby v2.7.2 meant that only bundler v2 was installed by
default. rspec_profiling v0.0.5 required bundler v1, but v0.0.6 relaxed
the dependency to allow for bundler 2 (see
https://github.com/foraker/rspec_profiling/commit/6ad1ec4e37).

[RUN ALL RSPEC] Fix migrate-from-v12.10.0 job not working with Ruby v2.7

See merge request gitlab-org/gitlab!46073

This test needs bundler v1.17.3 to work, so install that first.

The grpc and google-protobuf gems need to be updated to work with Ruby
v2.7. When we check out the v12.10.0-ee tag, we manually patch the
versions in the Gemfile before attempting to run the migration.

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.
