PromQL: ignore small errors for bucketQuantile (#13153 )

promql: Improve histogram_quantile calculation for classic buckets

Tiny differences between classic buckets are most likely caused by floating point precision issues. With this commit, relative changes below a certain threshold are ignored. This makes the result of histogram_quantile more meaningful, and also avoids triggering the _input to histogram_quantile needed to be fixed for monotonicity_ annotations in unactionable cases.

This commit also adds explanation of the new adjustment and of the monotonicity annotation to the documentation of `histogram_quantile`.
