[processor/metricsgeneration] Remove "experimental_" prefix (open-tel…

…emetry#35821)

The processor now has to be defined as `metricsgeneration` instead of
`experimental_metricsgeneration` in OTel collector configuration files.

 ## Description
 
-The metrics generation processor (`experimental_metricsgenerationprocessor`) can be used to create new metrics using existing metrics following a given rule. This processor currently supports the following two rule types for creating a new metric.
+The metrics generation processor (`metricsgenerationprocessor`) can be used to create new metrics using existing metrics following a given rule. This processor currently supports the following two rule types for creating a new metric.
 
 1. `calculate`: It can create a new metric from two existing metrics by applying one of the following arithmetic operations: add, subtract, multiply, divide, or percent. One use case is to calculate the `pod.memory.utilization` metric like the following equation-
 `pod.memory.utilization` = (`pod.memory.usage.bytes` / `node.memory.limit`)
