Fix error from ansible-lint versions >=6.11.0. (#4492)

* Fix error from ansible-lint versions >=6.11.0.

The JSON output format of ansible-lint has changed since
6.11.0. Issue locations can have either a 'positions' or
a 'lines' member, rather than just a 'lines' member as it
was before. This fix checks which member is present, and
passes that member name to subsequent dictionary lookups.

The error was caused by the following change:
https://github.com/ansible/ansible-lint/pull/2897

* Add ansible-lint test to check each type of ansible-lint issue json.

* Change long single-line JSON in ansible test into multiline JSON.

* Fix linting errors in ansible_lint.vim.
