patch 9.1.1000: tests: ruby tests fail with Ruby 3.4

Problem:  tests: ruby tests fail with Ruby 3.4
Solution: adjust expected output for Ruby 3.4
          (Yee Cheng Chin)

Vim's Ruby tests relied on explicit matching of output texts which are
fragile in design. Ruby 3.4 has changed the output slightly (using
'name' instead of `name', and also using more spaces in dictionary
printouts). Modify the Vim tests to be less fragile to such changes.
