CI: Run SSH Transport not on Ruby 3.4

On Ruby 3.4 it currently fails with:

```
Failures:

  1) Bolt::Transport::SSH when execution fails catches EMFILE error and raises helpful message
     Failure/Error:
       expect {
         yield
       }.to(raise_error { |ex|
         expect(ex).to be_a(klass)
         expect(ex.issue_code).to eq(issue_code)
         expect(ex.message).to match(message)
       })

       expected: nil
            got: "CONNECT_ERROR"

       (compared using ==)
     # ./spec/lib/bolt_spec/errors.rb:8:in 'BoltSpec::Errors#expect_node_error'
     # ./spec/integration/transport/ssh_spec.rb:158:in 'block (3 levels) in <top (required)>'
