Telemetryapi receiver types - excluding extension also drops platform

[jousby]

Describe the bug
As per the telemetryapi README there are three types of telemetry you can subscribe to ["platform", "function", "extension"]. If you exclude "extension" from this set it also turns off "platform".

Steps to reproduce

• Create and instrument a Lambda function
• Enable telemetryapi receiver for logs and traces and constrain the types for receiver to 'platform' and 'function'.

  telemetryapi:
    types:
      - platform
      - function

• Send logs to your OTEL backend of choice and check for the presence the platform log messages (platform.initStart, platform.initRuntimeDone)

What did you expect to see?
No logs for the extension.
Logs from the function
Logs from the platform for initStart and initRuntimeDone

What did you see instead?
Logs from the function only

What version of collector/language SDK version did you use?

0.19.0 (collector layer)
0.18.0 (nodejs layer)

What language layer did you use?
javascript
