Fix rubocop ``Naming/MethodName`` violations

Describe the Bug

Rubocop recently began failing because of Naming/MethodName violations in 2 files:

• lib/puppet-strings/yard/handlers/ruby/data_type_handler.rb
• lib/puppet-strings/yard/parsers/puppet/parser.rb

Since

• running rubocop --auto-gen-config does not (at this time) add these violations to the .rubocop_todo.yml; and
• adjusting these methods may have a downstream impact; and
• CI needs to be made green but not without recording a TODO to fix the violations

Then it was decided to explicitly

• add a #TODO to the files and a rubocop:disable Naming/MethodName; and
• raise this issue to record the requirement.

See PR https://github.com/puppetlabs/puppet-strings/pull/364

Expected Behavior

Rubocop should not throw any exceptions

Steps to Reproduce

Steps to reproduce the behavior:

1. Remove the rubocop:disable Naming/MethodName and rubocop:enable Naming/MethodName markers from the above files
2. Re-run on the terminal bundle exec rubocop --format github and note the exceptions as listed at the end of this issue.

Environment

• Version [e.g. 1.27.0]
• Platform [e.g. Ubuntu 18.04]

Additional Context

Start with lib/puppet-strings/yard/handlers/ruby/data_type_handler.rb and lib/puppet-strings/yard/parsers/puppet/parser.rb, reviewing the methods reported by Naming/MethodName and their downstream impact. Run bundle exec rubocop --format github after removing the disable markers. Done means the reported violations are resolved and RuboCop completes without exceptions.
