Remove deprecated fields from OTel ResolverSettings (#4803)

The `Providers` and `Converters` fields of `ResolverSettings` struct
were deprecated in [v0.99.0](https://github.com/open-telemetry/opentelemetry-collector/releases/tag/v0.99.0) (open-telemetry/opentelemetry-collector#9516)
and removed in [v0.101.0](https://github.com/open-telemetry/opentelemetry-collector/releases/tag/v0.101.0).
This refactoring is required before updating to OTel v0.101.0.
