Modified both the Rust and Go OTEL plugins to use slashes instead of dots
in the family field, enabling hierarchical grouping in the dashboard.

For example:
- Before: otel.dotnet.exceptions
- After: otel/dotnet/exceptions

Also fixed a pre-existing bug in convert_test.go where Convert was called
instead of convert (lowercase).

Removed modifications to Go otel-collector code as per review feedback.
The OTEL plugin is Rust-only. The fix only needs to replace dots with
slashes in the family field in the Rust plugin.

The family field should just use the metric name with dots replaced by slashes,
without the otel/ prefix (e.g., dotnet/exceptions instead of otel/dotnet/exceptions).
