MapConverter does not get initialized if OTEL_SDK_DISABLED is set to true

[StiviiK]

Describe the bug

When the SDK gets disabled via Environment Variable OTEL_SDK_DISABLED but the OTEL_RESOURCE_ATTRIBUTES or otel.resource.attributes env/configuration is present, the application fails to start. Due to the MapConverter not being enabled/present.

Description:

Failed to bind properties under 'otel.resource.attributes' to java.util.Map<java.lang.String, java.lang.String>:

    Property: otel.resource.attributes
    Value: "service.name=workflow-backend-dev,service.version=3c8f9ce9"
    Origin: System Environment Property "OTEL_RESOURCE_ATTRIBUTES"
    Reason: org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [java.util.Map<java.lang.String, java.lang.String>]

Action:

Update your application's configuration

Steps to reproduce

1. Set up a Spring Boot sample project with OTEL as specified in https://opentelemetry.io/docs/languages/java/automatic/spring-boot/
2. In envvars, include a sample OTEL_RESOURCE_ATTRIBUTES map (e.g. var1=sample1,var2=sample2), and set env OTEL_SDK_DISABLED to true.
3. Run the application.

Expected behavior

The application starts up and/or ignores the configuration property.

Actual behavior

The application fails on
