Specs pass under ruby 3.3 and 3.4

[aramprice]

Some textual output in Ruby 3.4 has been change which caused hard-coded expectations to be incorrect, e.g. Hash's string representation changed spacing.
This commit resolves this difference by relying on Ruby's interpolation for objects, rather than hard-coding a specific iterpolation into specs.

Should fix (most) failures in: #2748
