Update CI to latest (#40)

Add Ruby 3.4 and 4.0 to the CI matrix and update the Gemfile where needed. `gem_generator` 1.0 supports only Ruby 3.2 and above, so remove Ruby 3.0 and 3.1 from the CI matrix.

Fix the bundle outdated test so it passes. Currently, rspec depends on diff-lcs 1.x, and diff-lcs 2.0 was recently released, which causes bundle outdated to fail. Add --only-explicit as a workaround.
