Non-existent version of paddlepaddle in requirements

[JeffreyEnglish]

Describe the bug
Installing layoutparser[paddledetection] requires "paddlepaddle==2.1.0". But paddlepaddle does not have a version 2.1.0, so the install fails. I believe the correct version should be "paddlepaddle==3.1.0"

Checklist

1. I have searched related issues but cannot get the expected help.
2. The bug has not been fixed in the latest version, see the Layout Parser Releases

Environment

2. Please show the Layout Parser version2.
   layoutparser[effdet,layoutmodels]>=0.3.4

Error traceback
No solution found when resolving dependencies for split (python_full_version >= '3.12' and python_full_version < '3.12.4' and platform_system == 'Darwin'):
╰─▶ Because only layoutparser[paddledetection]<=0.3.4 is available and layoutparser[paddledetection]==0.3.4 depends on paddlepaddle==2.1.0, we can conclude that layoutparser[paddledetection]>=0.3.4 depends on
paddlepaddle==2.1.0.
And because there is no version of paddlepaddle==2.1.0 and your project depends on layoutparser[paddledetection]>=0.3.4, we can conclude that your project's requirements are unsatisfiable.
