Missing Attributes

[csandrew-dev]

If an attribute, such as the description is missing, the script error instead of removing that attribute from the generated json file.

example:
https://developer.apple.com/documentation/appleschoolmanagerapi/errorlinks

uv run schemer.py https://developer.apple.com/documentation/appleschoolmanagerapi/errorlinks ./asm/schema

produces:
