Pale Moon 33.7.0: bugfix and security release

Pale Moon Browser 33.7.0 has been released as a development, bugfix, and security update. Key changes include added support for CSS two-location color stop logic, updates to the vendored JPEG XL and FFmpeg libraries, and several security improvements, such as enhanced safety checking and fixes for NTLM authentication and DOMRect compliance issues. Notably, a new preference has been introduced for Windows users to control shortcut link handling in file open dialogs, addressing a low severity security issue while maintaining usability.
