Ensure we're using the correct @ignore phpDocumentor tag to mark elements that should be skipped when parsing.

Up to this point, various core elements' DocBlocks incorrectly included an `@internal` tag as a means for skipping the parsing process. When paired with a description (inline or otherwise), `@internal` is a valid tag meant to provide internal-only context, but not necessarily to skip parsing the entire element.

See #30987.
