Issue description

In section 9.1 we have extra backticks appearing in the text under the heading "Reviewing Alternative Modules to Manage Packages":

1. A single backtick on the line reading - "ansible_facts['distribution_major_version'] >= '8'`"

1. A single backtick below that, on the line reading `ansible.builtin.yum:
2. A pair of backticks on the line reading - "ansible_facts['distribution_major_version'] <= `'7'`"

None of these backticks are valid syntax and they must all be removed.
