Adopt new `io.opentelemetry.semconv:opentelemetry-semconv` lib

[cyrille-leclerc]

Description:

Adopt new io.opentelemetry.semconv:opentelemetry-semconv lib without yet replacing http.url and http.method by url.full and http.request.method as we will want to align with the OTel Java Auto Instrumentation and support -Dotel.semconv-stability.opt-in=http... to embrace the new semantic conventions

Existing Issue(s):

• https://github.com/open-telemetry/opentelemetry-java-contrib/issues/1044

Testing:

None as there are no change in the behavior of the instrumentation

Documentation:

None as there are no change in the behavior of the instrumentation

Outstanding items:

Not really outstanding but we will have to add support for the new HTTP Semantic Conventions, url.full and http.request.method and we want to do it the same way the Otel Java Auto Instr implementing -Dotel.semconv-stability.opt-in=http... as described in https://github.com/open-telemetry/opentelemetry-java-instrumentation/releases/tag/v1.27.0
