🦉 Prototype Pollution

[graymalkin77]

This is a patch upgrade that includes security fixes and bug corrections.

Highlights:

• v3.3.2: This version addresses a potential bypass in jsdom, a prototype pollution issue, and fixes lenient configuration parsing.
• v3.3.1: This version extended the ADD_FORBID_CONTENTS setting and corrected the ESM import syntax.

Potential Impact:
The fix for "lenient config parsing in _isValidAttribute" in version 3.3.2 introduces stricter validation. While this is a bug fix, it could be a behavioral change for any implementation that was unintentionally relying on the previous, more lenient parsing. This change warrants a medium risk assessment.

Recommendation:
Verify that any custom configurations for DOMPurify attributes are still behaving as expected after the upgrade.
