Inline rule apply to other files

[maruTA-bis5]

Describe the bug Execute htmlhint cli sometimes happenes false negative when some file uses inline rules. I saw that HTMLHint.verify(content, ruleset) changes ruleset's value.

To Reproduce Steps to reproduce the behavior:

1. Execute npx htmlhint **/*.html
   • Need multiple files. One of file uses inline rules, other files don't use inline rules.

There are reproducer: https://github.com/maruTA-bis5/htmlhint-inline-rules-breaks-cli

Expected behavior Inline rules should not apply to other files.

Additional context HTMLHint version: 0.14.1
