Attempt to import "annotatable" block content into library fails

[ormsbee]

Reproduction steps:

1. Create a new course and import the following file into it: annotatable-course.tar.gz
2. Import that new course into a library using the library's Tools -> Import -> Import Course functionality.

It will raise AttributeError: 'super' object has no attribute 'parse_xml_new_runtime' while processing the content of the AnnotatableBlock for import. The error log:

The rest of the content of the course will import properly.

FYI @kdmccormick, @bradenmacdonald, @crathbun428, @jmakowski1123

I don't expect that this is a blocker. Just something I ran into while debugging other things today.

[kdmccormick]

Took the quickest look. It's likely a regression from xblock extraction. Quick note, the parse_xml_new_runtime error is a red herring--that's an expected exception for any block that doesn't opt into simpler XML parsing when in the openedx_content runtime. The core issue is that super().parse_xml is not defined. https://github.com/openedx/xblocks-core/blob/main/xblocks_contrib/legacy_utils/xml_utils.py#L454-L463

[kdmccormick]

I'll have Aximprovements take a look.

@ormsbee Thanks for flagging the issue

@kdmccormick I have created the PR for the fix of the issue
