Apply does not work on local transport with bundled-ruby=false for latest puppet 7 agents
Describe the Bug
When not using bundled-ruby for the local transport, it is impossible to load puppet in puppet 7.26.0 for example because the concurrent ruby gem is different between that which is shipped in the bolt package vs that which is shipped in the agent package.
Expected Behavior
Ideally the local transport can support both puppet 7 and 8 agents. Currently bolt is a puppet 7 based, for now it should continue to work with puppet7.
Steps to Reproduce
configure bundled-ruby: false in local config and run bolt apply -e "notify {foo: }" -t locah://localhost.
Environment
root@warmish-workman:~/foo# bolt --version
3.27.2
root@warmish-workman:~/foo# puppet --version
7.26.0
root@warmish-workman:~/foo# find / -name concurrent.rb
/opt/puppetlabs/bolt/lib/ruby/gems/2.7.0/gems/concurrent-ruby-1.1.10/lib/concurrent-ruby/concurrent.rb
/opt/puppetlabs/bolt/lib/ruby/gems/2.7.0/gems/puppet-7.24.0/lib/puppet/concurrent.rb
/opt/puppetlabs/puppet/lib/ruby/gems/2.7.0/gems/concurrent-ruby-1.1.9/lib/concurrent-ruby/concurrent.rb
/opt/puppetlabs/puppet/lib/ruby/vendor_ruby/puppet/concurrent.rb
Additional Context
In bolt-vanagon we set the ruby runtime to bolt-specific env (notably gem_path etc), we then use that in local transport https://github.com/puppetlabs/bolt/blob/6ff65051b45207e7de363a4c9ce0be6b6b4761f8/lib/bolt/transport/local/connection.rb#L74-L78 when not using bundled env. This requires that gems are compatible between the agent and bolt deps.
This actually was an issue with the local transport itself (see linked PR). I went ahead and bumped gem deps anyway https://github.com/puppetlabs/puppet-runtime/pull/735
