fix: correct phpstan errors and update schema urls

This commit includes several modifications:

• Removed the ignoreErrors directives in phpstan-baseline.neon as the corresponding issues have been resolved
• Updated 'itemtype' URL from 'http://' to 'https://'
• Removed an obsolete comment block above the getSite method in Timeline.php
• Added variable documentation in types/timeline.php to clarify variable types and avoid phpstan errors.
