[prometheus] Stabilize Prometheus -> OTLP: Summaries #4749
Description
What are you trying to achieve?
Stabilize https://opentelemetry.io/docs/specs/otel/compatibility/prometheus_and_openmetrics/#summaries
Similar to #4745:
It would be helpful to re-phrase this section to not rely as heavily on text format suffixes. E.g.
Lines with _count and _sum suffixes are used to determine the summary’s count and sum.
Should become something like:
The summary count must be used to determine the summary's count. For the Prometheus text format, the count is a separate series of the form <metric family name>_count.
