Updated recipe for Pandemy to noarch: python
Updated recipe for Pandemy to noarch: python

- Added noarch: python to the build section.
- Added python >=3.8 to the host requirements section.
- Removed the requirements build section. There are no specific build requirements for Pandemy.

Pandemy does not need to be built differently for specific platforms meaning noarch makes sense.
