This reverts commit d2eef4b7867578df302cfa9d7c97eebbef8d9ee4.

Because `syntax_suggest` is a default gem you can get conflicts when working on this project with Ruby 3.2+. To fix conflicts you can disable loading `syntax_suggest` as a default gem by using then environment variable `RUBYOPT` with the value `--disable=syntax_suggest`. The `RUBYOPT` environment variable works the same as if we had entered those flags directly in the ruby cli (i.e. `ruby --disable=syntax_suggest` is the same as `RUBYOPT="--disable=syntax_suggest" ruby`). It's needed because we don't always directly execute Ruby and RUBYOPT will be picked up when other commands load ruby (`rspec`, `rake`, or `bundle` etc.).

There are some binstubs that already have this done for you. Instead of running `bundle exec rake` you can run `bin/rake`. Binstubs provided:

- `bin/rake`
- `bin/rspec`

The cause was in how Gem::SystemExitException initializes itself.  It
didn't pass an exit code to the super method.  See the document of
SystemExit.new() for details.
