docs: mention priority ordering in sort-attrs documentation

[AdamVig]

A coworker expressed confusion about why type would be sorted before class when the rule's error message says "Attributes should be sorted alphabetically." Updating the rule's error message and documentation to mention the priority sorting behavior should avoid future confusion.

Pull Request Overview

Updates documentation and error messages for the sort-attrs ESLint rule to clarify that attributes are sorted by priority first, then alphabetically, rather than just alphabetically. This addresses confusion where users expected pure alphabetical sorting but observed priority-based ordering (e.g., type before class).

• Updated rule description and error message to mention priority ordering
• Modified documentation to reflect the actual sorting behavior
