fix(pack): Add support for additional Ansible directory structures in ansible's path_regex, and correct docs

[lucazz]

📑 Description

This PR further extends the regex used to match common Ansible paths, some of them are documented best practices, even:

We're adding the following paths to the regex:

• ansible/
• playbooks/
• group_vars/
• host_vars/
• vars/
• tasks/

ℹ Additional Information

Here's an example on how nested variables look like in the wild:

├── ansible
│   ├── group_vars
│   ├── host_vars
│   ├── roles
│   │   ├── foo
│   │   │   ├── defaults
│   │   │   ├── tasks
│   │   │   └── vars
│   │   ├── bar
│   │   │   ├── defaults
│   │   │   ├── tasks
│   │   │   ├── templates
│   │   │   └── vars
│   │   └── baz
│   │       ├── vars
│   │       ├── defaults
│   │       └── tasks
│   └── vars
└── tests
    └── charts
        ├── hello
        │   └── templates
        │       └── tests
        └── oauth2
            └── templates
                └── tests

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Entry returns a single plugin spec with the new plugin as the only top level spec (not applicable for recipes or packs).

• Proper usage of opts table rather than setting things up with the config function.

• Proper usage of specs table for all specs that are not dependencies of a given plugin (not applicable for recipes or packs).
