Update browser_session definition for newer BU vers. (#55)

Updating the browser_session definition to reflect viewport handling changes in recent versions of browser-use. The BrowserSessionCustomResize workaround is no longer required in the latest release. It remains available for users who choose to run older versions of browser-use, where custom resizing is still necessary.
