Updates verify workflow to use shared pipeline

[cgranleese-r7]

This updates this workflow to make use off the shared pipeline added as part of rapid7/metasploit-framework#20001.

Initially this PR will point at these new pipelines on my @cgranleese-r7 repository for testing. Once this is landed, I will rebase this PR.

Ruby 3.4

I also added bigdecimal to the gemspec as it is not part of the default gems starting from Ruby 3.4.0(https://www.ruby-lang.org/en/news/2023/12/25/ruby-3-3-0-released/). This can be pulled out into another PR if that is preferred.

Verification

• Ensure CI passes
• Testing output flows as expected
