Clarify Collector internal metric names by version

[tiffany76]

What needs to be changed? With release v0.106.1, the names of Collector internal metrics are handled differently, depending on whether they are generated from Collector components (prefixed with otelcol_) or instrumentation libraries (not prefixed with otelcol_).

The list of metrics is correct as-is, but we should add a note that clarifies that versions of the Collector prior to v0.106.1 append the otelcol_ prefix to all internal metrics, both instrumentation library-generated as well as component-generated.

What is the name + path of the page that needs changed? https://opentelemetry.io/docs/collector/internal-telemetry/#lists-of-internal-metrics
