Pull Request Overview

This PR adds pattern support to the priority option in the sort-attrs ESLint rule, addressing issue #404. The enhancement allows users to specify regular expression patterns to match attribute names in addition to exact string matches.

• Extends the priority option schema to accept objects with a pattern property containing regex patterns
• Implements pattern matching logic using RegExp to evaluate attribute names against priority patterns
• Adds comprehensive test coverage for pattern-based priority sorting scenarios

Creating RegExp objects during rule execution can impact performance. Consider validating and compiling patterns once during rule initialization or caching compiled regexes to avoid repeated compilation for the same patterns.
