No errors at deployment when using runtime v4 with managed functions

[sinedied]

Before filing this issue, please ensure you're using the latest CLI by running swa --version and comparing to the latest version on npm.

Are you accessing the CLI from the default port :4280 ?

• No, I am using a different port number (--port) and accessing the CLI from that port
• Yes, I am accessing the CLI from port :4280

Make sure you are accessing the URL printed in the console when running swa start!

ℹ️ NOTE: Make sure to enable debug logs when running any swa commands using --verbose=silly

Describe the bug
When using runtime v4 with a JS/TS managed functions API, no error is shown during deployment with SWA CLI (shows success message) but no functions are actually deployed.

Note: Now, I know that v4 runtime is currently not supported, but I didn't at the time and was caught trying to understand why my functions were missing for hours.

To Reproduce

1. Create a SWA project with a function API using JS v4 runtime
2. Run SWA deploy

Expected behavior
A warning or error message should be displayed to the user to indicate that runtime v4 is not currently supported.
