Debug fails because SharePoint Online Connector Triggers template generates invalid azure-functions dependency

[v-ruizh]

OS: Win 11 x64
Build Version: 20260708.2

Repro Steps:

1. Open Template Gallery.
2. Create a project using SharePoint Online Connector Triggers (Python + AZD + Bicep) template.
3. Open the generated project.
4. Initial the project.
5. Debug the project.

Expect:
Debug should complete the dependency installation successfully and start the Function app.

Actual:
Debug fails because the generated requirements.txt references azure-functions>=2.2.0b4, which cannot be found on PyPI.

More Info:

1. This is the generated requirements.txt in project.
   
2. The similar issue still reproduces for Simple Agent QuickStart (Python + AZD + Bicep) project (azure-functions>=2.2.0 in the generated requirements.txt).
3. Update the requirements.txt to azure-functions, still fail to debug the project.
