[PROF-13115] Bootstrap installing dependencies on Ruby 4.0.0-preview2#5092
Conversation
**What does this PR do?** This PR adds the `ruby-4.0.gemfile` file that's needed for running `bundle install` on Ruby 4.0.0-preview2. The contents of this file being added are copy/pasted from `ruby-4.0.gemfile` with no changes. I did not add or change anything on purpose: This is a very minimal part of the Ruby 4 CI support being prepared in #5084 but unlocks local development with Ruby 4.0. I suggest we keep adjustments/cleanups/etc for that later PR where we officially add Ruby 4.0 to our CI. **Motivation:** Without this file it's impossible to do local development on Ruby 4.0.0-preview2. It also came up in <DataDog/datadog-ruby_core_source#19>: we want to check if the profiler extension compiles on Ruby 4.0 and we're not able without this file. With this PR we can run `bundle install` and start running tests and tackling what's missing. **Additional Notes:** N/A **How to test the change?** Validate that it's possible to run `bundle install` on Ruby 4.0.
