Create OTel IdGenerator tests

[brunobat]

Description

We are missing IdGenerator tests to prove the correct integration.
The tests were working with AWS ID Generator and we don't want that dependency on the main extension.

See: io.quarkus.opentelemetry.deployment.OpenTelemetryIdGeneratorTest

Implementation ideas

No response

We need to create an ID generator that is not AWS dependent, use it and see if it works.

In relation to the AWS ID itself it would be nice to have a test project for AWS lambdas that could also use this, however, this a much bigger task.

Gonna have a look at the ID generators.
