Description

I am importing github.com/open-telemetry/opentelemetry-tutorials/trace-receiver/tailtracer but I feel this package does not exist anymore

also on a side note the generated components.go imports two more packages by default. There are not used in the tutorial as we work on a receiver but they should be part of the code snippet.

"[go.opentelemetry.io/collector/component](http://go.opentelemetry.io/collector/component)"
"[go.opentelemetry.io/collector/connector](http://go.opentelemetry.io/collector/connector)"

I realised that when trying to initialise the collector with tailtracer MakeFactoryMap function has moved under otelcol instead of extension

`factories.Extensions, err = extension.MakeFactoryMap(` throws an error. 

`factories.Extensions, err = otelcol.MakeFactoryMap[extension.Factory](` does compile 

At the moment I am not able to get the custom collector to run so I have probably missed other changes

Let me know which info you need my go.mod requires looks like the following :

require (
	go.opentelemetry.io/collector/component v1.30.0
