Collect user provided tracer name, version and schemaURL

[RonFed]

When the WithGlobal InstrumentationOption is used, use the user provided tracer name.

The Tracer name, version, and scope are the three identifying fields. By only using the tracer name here we are going to have collisions with the wrong tracer being used. The version and schema URL need to also be determined and used in the tracer resolution path.

I added the version. Regarding the schema, I noticed it was added recently (open-telemetry/opentelemetry-go#5426) to the traces map that the probe is reading, so currently it is not being read by the probe. We can add it once a new release of otel-go is out (and then make the adjustment in the probe to only look for the schema in version newer from that release).

LGTM!

@MrAlias I think this will break once the new version of otel-go is released (since the tracers' map key size will change), so maybe it is better to wait with this PR. Once the new version is out I will add code to adjust the key size

Working on otel release here: open-telemetry/opentelemetry-go#5569

@RonFed Releases v1.28.0/v0.50.0/v0.4.0 was made yesterday. This should be unblocked.

Looks good to me overall. Minor nits.

Looks like some tests need to be updated for the added schema URLs.
