[Menghua1]

Describe:
Failed to start Functions host with mvn azure-functions:run due to incorrect extensionBundle version format in host.json. The correct format should be 4.29.0. See screenshot below.

Repro Steps:

1. Run azd init --template Azure-Samples/remote-mcp-functions-java.
2. Run mvn clean package.
3. Run mvn azure-functions:run.

Environment:

• OS: Windows
• Azure Functions Core Tools Version: 4.5.0.
• Azd version: azd version 1.21.3 (commit b01891fc63b1faf9a9633cdc630deab0b4d569c4).

Expected behavior:
The command mvn azure-functions:run successfully starts the Functions host.

Suggestion:
Update 4.29. to 4.29.0 in the host.json file.
