Allow client setting to sort the plugin names in autocompletion based on user preference

[ganeshrn]

Problem

Currently the sort preference for auto completion is hardcoded.
Reference https://github.com/ansible/ansible-language-server/blob/main/src/providers/completionProvider.ts#L148

Allow user setting to provide a preference for sort order. For example

 "ansible.autoComplete.sortOrder": ["plugin", "fqcn", "collection", "namespace"]

Solution
