Fix TypeError when using CI json-cid endpoint

[lucasmarchd01]

This pull request fixes a TypeError in the get_suggested_fulltext function by adding exception handling for TypeError.

Previously, the function raised a TypeError when attempting to access a key in json_response that was None for chants that don't have a full text.

Also adds some black formatting changes.

Fixes #1690

In situations like this I generally prefer the .get() method, since it doesn’t raise anything. You can also chain them by making the default an empty dict.

suggested_fulltext:Optional[str] = json_response.get("info", {}).get (“field_full_text")

The only problem I came across when testing this is that sometimes "info" will be None leading to an AttributeError on the second chain. So we'll have to do something like this instead:

    info: Optional[dict] = json_response.get("info", {})
    if not isinstance(info, dict):
        return None
    suggested_fulltext: Optional[str] = info.get("field_full_text")
    return suggested_fulltext

This will do pretty much the same thing without needing the isinstance check...

info: dict = json_response.get("info", {}) or {}
return info.get("field_full_text")
