Plugin 2022.3 causes an IDE Error when a PyPI project has an empty comment

[ZeroPointMax]

Describe the bug

If the PyPI package comment is empty, Requirements will throw an exception because it cannot decode a null value

kotlinx.serialization.json.internal.JsonDecodingException: Unexpected JSON token at offset 189126: Expected string literal but 'null' literal was found at path: $.releases['0.75.1'][0].comment_text
Use 'coerceInputValues = true' in 'Json {}` builder to coerce nulls to default values.
