name[casing] lint for notify directives should take into account <role name> : <Task name> syntax

[bsteinb]

Summary

The notify: directive for running handlers supports a syntax <role name> : <Task name> to help avoid name collisions between handlers from different roles.

As role names are usually all lower case, the changes in #4149, which check the casing of the first letter in the argument to a notify: directive, cause failures when this <role name> : <Task name> syntax is used.

OS / ENVIRONMENT

ansible-lint --version
ansible-lint 24.5.0 using ansible-core:2.16.6 ansible-compat:24.5.1 ruamel-yaml:0.18.6 ruamel-yaml-clib:0.2.8

• ansible installation method: pip
• ansible-lint installation method: pip

STEPS TO REPRODUCE

Have a role role with a tasks/main.yml as follows:

- name: Task
  ansible.builtin.debug:
    msg: Task
  notify: 'role : Handler'

and a handlers/main.yml as follows:

- name: Handler
  ansible.builtin.debug:
    msg: Handler

Then run ansible-lint on role/tasks/main.yml.

Desired Behavior

No failures.

Actual Behavior

The argument of the notify: directive fails the name[casing] lint, even though it is legal syntax and the handler and role names individually follow conventions and pass ansible-lint's checks.

name[casing]: Task notify 'role : Handler' should start with an uppercase letter.
roles/role/tasks/main.yml:1 Task/Handler: Task

EDIT: My point is covered by #4168. Sorry for the noise :)

The new linting rule also impacts the use of topics using the listen keyword as described in the doc.
The example in the doc would fail the linting.
