getDevPythonVersion() hardcodes minor: 0, breaks local dev with uv >= 0.10.11

Bug

vercel dev fails for Python serverless functions when uv >= 0.10.11 is installed.

Root cause

getDevPythonVersion() in packages/python/src/index.ts hardcodes minor: 0:

function getDevPythonVersion() {                                                                      
  return {                                      
    major: 3,                          
    minor: 0,  // ← always passes --python 3.0 to uv
    ...                                             
  };                                                                                                  
}   
                                                                                                      
This causes vercel dev to call uv venv --python 3.0, which uv 0.10.11 rejects:
                                                                                                      
error: Invalid version request: Python <3.7 is not supported but 3.0 was requested.
                                                                                                      
Older uv versions accepted 3.0 as "any Python 3", but uv 0.10.11 treats it as a literal version.
                                                                                                      
Steps to reproduce                              
                                       
1. Install uv >= 0.10.11
2. Run vercel dev on a project with Python serverless functions
3. Any API call to a Python function returns HTTP 500
                                                                                                      
Expected behavior
                                                                                                      
Dev server builds Python functions successfully.                                                      
                                       
Suggested fix                                                                                         
                                                
Use the actual system Python version in getDevPythonVersion(), or omit the --python flag in dev mode  
since pythonPath: "python3" already resolves the correct binary.
                                                                                                      
Environment                                                                                           
                                       
- Vercel CLI: 51.5.1                                                                                  
- uv: 0.10.11                                   
- OS: macOS

Start in packages/python/src/index.ts at getDevPythonVersion(), then reproduce with uv >= 0.10.11 using vercel dev on a project with Python serverless functions. Verify that development builds succeed and Python function API calls no longer return HTTP 500.
