Prevent InvalidCharacterError by correctly rendering x-cloak attribute

[pascalberski]

Description

This PR addresses a bug that caused an InvalidCharacterError: Failed to execute 'setAttribute' on 'Element': '0' is not a valid attribute name.

The root cause was that 'x-cloak' was added as a value without an explicit key in PHP arrays responsible for generating HTML attributes (e.g., in getTopLevelAttributesArray()). This led to PHP assigning a numeric index, which was then incorrectly used as the attribute name.

The fix changes the array definition from ..., 'x-cloak', ... to ..., 'x-cloak' => '', .... This ensures x-cloak is rendered as a proper attribute (x-cloak=""), resolving the JavaScript error and allowing Alpine.js to function as expected.
