Pull request overview

This PR updates the HTMLHint schema to allow two rules (attr-lowercase and attr-value-no-duplication) to accept either boolean or array types, matching their actual behavior in HTMLHint.

• Changed attr-lowercase and attr-value-no-duplication from boolean-only to accepting boolean or array types using anyOf
• This aligns the schema with HTMLHint's actual API where these rules can accept arrays of attribute names

• The array type definition is incomplete. According to the HTMLHint documentation, the array should contain attribute names as strings. Add an items schema to specify that array elements should be strings.

    "attr-value-not-empty": {
      "description": "Attribute must set value.",
      "type": "boolean",
      "default": false

Test coverage should be added for the new array type functionality. The existing test file only covers boolean values. Add test cases showing the array usage for both attr-lowercase and attr-value-no-duplication rules.
