Allow ruby version 3.4 in gemspec

[mjankowski]

Resolves #103

[mjankowski]

Looks like a quoting change between 3.3 and 3.4 leads to change in output, which causes one failure. Specifically:

This is generated under 3.3 and earlier...

      # ./spec/spec_spec.rb:2:in `block (2 levels) in <top (required)>'

But under 3.4...

      # ./spec/spec_spec.rb:2:in 'block (2 levels) in <top (required)>'

(Note the change in ` to ' there)

Not sure how critical that format aspect is, or full context on that spec.

Hey @mjankowski! I made an attempt to fix the failing test, feel free to cherrypick my commit a7ebab0 here

[mjankowski]

Thanks -- going to stand by on maintainer feedback re: desired path here, but will grab your commit if we're fine w/ that level of precision (again I dont fully understand context here). Seems like it more or less preserves intentions while being more flexible on apparently-version-specific output format.

Hey @briandunn!! First of all, thanks for maintaining this gem, it's awesome!

Are you ok with the approach taken here?
The 'issue' is regarding this change to Ruby:

Use a single quote instead of a backtick as a opening quote. [Feature #16495]

ruby/ruby#9608

Oh yeah, also - separately from this formatting issue ... I can confirm that actually using/running flatware on 3.4.1 (with this PR branch allowing bundle) appears to be totally fine! My suite runs are as parallel as they've ever been.

👋 Two things:

1. Here's an alternative solution to the failing test: 4957ef9 just to have an additional option available
2. I've also verified that flatware works with rspec and ruby 3.4.1 using this branch (commit 7f03671)

[mjankowski]

Updated to add one of those commits which also fixes the failure. Should be passing now.

@briandunn whenever you are back from holiday let me know if this makes sense or you'd prefer some other approach.

Thank you so much! Loosening the assertion was exactly what I had in mind when I saw the initial failures. nice.
