Sync Gemfile.lock Ruby version and add checksums to Gemfile.lock

Description

Proposing we sync the Ruby version in the Gemfile.lock with the version in .ruby-version and add checksums to the Gemfile.lock as modern best practices.

Follow up to #1427

Ruby version in Gemfile.lock

RUBY VERSION (optional)

The Ruby version specified in the Gemfile, when this Gemfile.lock was created. If a Ruby version is specified in a .ruby_version file instead this section will not be present (as Bundler will consider the Gemfile / Gemfile.lock agnostic to the installer's Ruby version).

While we're at it, we might as well add the checksums to the lockfile, that's the new default when you create a lockfile.

It would be nice to fix this upstream though.

Have seen that. Sure thing. I can take a look at doing that in this PR.

Do you mean so that Bundler automatically keeps the Gemfile.lock Ruby version in sync with .ruby-version?
