Description

2 bugs:
1. convert_to_beam_type passes typing.NamedTuple as-is. The code that's supposed to convert it to Any is broken (and the test is buggy too).
Fix: https://github.com/apache/beam/pull/9754/files#diff-9b2eac354738047adddd44814d4b429cR247

2. Possible bug: collections.NamedTuple instances should also be converted to Any, or Tuple[Any, Any, ..], if other static types checker do this as well.
