[pypi] Fix Python package descriptions exceeding 512 character limit (#1949)

Shorten cuegui package description from 574 to 490 characters to comply
with PyPI's 512 character limit for summary/description field. This
fixes test upload failures caused by descriptions being too long.

All 8 Python packages now have descriptions under the 512 character
limit:
- cueadmin: 260 chars
- cuegui: 490 chars (previously 574)
- cueman: 237 chars
- cuesubmit: 223 chars
- proto: 99 chars
- pycue: 195 chars
- pyoutline: 233 chars
- rqd: 85 chars
