Add dependencies removed from default gems in Ruby 3.4.0

[sparr]

Motivation

Ruby 3.4.0 removed a bunch of default gems. The ones used by squib need to be specified.

/usr/lib/ruby/3.4.0/did_you_mean/core_ext/name_error.rb:11: warning: bigdecimal is not part of the default gems starting from Ruby 3.4.0. Install bigdecimal from RubyGems.
<internal:/usr/lib/ruby/3.4.0/rubygems/core_ext/kernel_require.rb>:136:in 'Kernel#require': cannot load such file -- bigdecimal (LoadError)
        from <internal:/usr/lib/ruby/3.4.0/rubygems/core_ext/kernel_require.rb>:136:in 'Kernel#require'
        from /home/sparr/.local/share/gem/ruby/3.4.0/gems/squib-0.19.0/lib/squib/commands/make_sprue.rb:4:in '<top (required)>'

/usr/lib/ruby/3.4.0/did_you_mean/core_ext/name_error.rb:11: warning: csv is not part of the default gems starting from Ruby 3.4.0. Install csv from RubyGems.

I also included abbrev which is a new dependency of highline. I opened an issue for them to backport their dependency fix to version 2.1 but that's a long shot. JEG2/highline#280

This PR failed tests due to Ruby 3.1 perceiving duplicate dependencies on the then-default gems. I pushed some attempts to address that, but now Github has stopped running checks on the PR?

I accidentally started working from master, not dev.
