Add `go.mongodb.org/mongo-driver/v2` specific instrumentation

[MrAlias]

v2 specific instrumentation needs to be added in addition. Support for v1 needs to continue.

Currently the Mongo DB instrumentation has no owner. The new owner needs to assume this task or we should close this along with https://github.com/open-telemetry/opentelemetry-go-contrib/issues/5551 if we do not land on ownership.

I did a copy/paste implementation using the new mongo-driver/v2 library: https://github.com/open-telemetry/opentelemetry-go-contrib/pull/6539

I chose the folder structure to match the golang package name.

@MrAlias I would be happy to help review #6539.

I would be happy to help review

Feel free to do so, as that's definitely a good way forward being code owner :)

I can see that #6539 is merged and Release notes for v1.36.0 mentions that "Add instrumentation support for go.mongodb.org/mongo-driver/v2" but I dont see a release version of this package.

go.opentelemetry.io/contrib/instrumentation/go.mongodb.org/mongo-driver/v2/mongo/otelmongo is listed under excluded-modules in versions.yaml cc @prestonvasquez @dmathieu

If you look at the PR merging the new instrumentation, we decided not to ship it for now. That doesn't prevent using it. You can use commit hashes as a go module version.

This was shipped in https://github.com/open-telemetry/opentelemetry-go-contrib/tree/main/instrumentation/go.mongodb.org/mongo-driver/v2/mongo/otelmongo
