Maintain correlation_id across Sidekiq retries

See merge request !121

chore: remove Context.known_log_keys

See merge request !122

Previously this code was overriding the correlation_id in the `job`
hash. That's because retries were generating a new context and this new
context had a new random `correlation_id`.

Now we take the previous `correlation_id` into account when generating a
new context.

This resolves gitlab-org/gitlab#440700

Since 9c62fa8f, labkit does not know
what keys might be part of the context. But I forgot to remove this
dead method.

The method as it currently stands would fail, since the `KNOWN_KEYS`
constant does not exist.

chore: explicitly call out the gem name and namesquatting of labkit-ruby

See merge request !115

This calls out the gem name in the docs, so people don't go looking
for labkit-ruby on RubyGems.org. It also adds a blurb about the gem
we're namesquatting to avoid confusion.

Update pg_query version to 4.2.1

Add and fix Ruby 3.1 and 3.2 to CI builds

See merge request !113

rspec and rspec-parameterized gems had to be updated to make keyword
argument matching work properly.

In addition, the spec needed to be updated so that
`Labkit::Tracing::Factory.create_tracer` was passing in a Hash instead
of keyword arguments.

Refactor .gitlab-ci.yml for parallel matrix builds and add
caching for vendored gems.
