[Python APIView] Parser renders invalid attribute annotation with '~.' prefix (e.g. '~.code: str')

Bad code snippet:

~.code: str

Description:
The language parser is rendering an attribute annotation with a leading "~." prefix, producing invalid Python syntax in the APIView output. This appears in the azure-core package (ODataV4Error member) and was identified as a rendering bug by the architect. The parser should not insert the "~." prefix; the attribute should be displayed as a normal identifier with a type annotation.

Good code snippet:

code: str

Start with the Python APIView language parser and trace how the azure-core ODataV4Error member is rendered. Reproduce the bad `~.code: str` output, then verify that the member is emitted as `code: str` without the leading prefix and remains valid Python.
