fix: fix formatting rules name

[azu]

Previously, dist/* can not define correct RULE_NAME in some rules.

This PR use hard code RULE_NAME instead of getFilename util

1. replace getFilename with <filename>
2. remove getFilename usage

#!/bin/bash

for file in $(ls -1 src/rules/*.ts); do
  echo "Processing $file"
  sed -i '' -e "s#getFilename(import.meta.url)#'$(basename ${file%.*})'#g" $file
done

fix #509
