Summary

Fix the amplitude estimation algorithms in the amplitude_estimators module for the usage
with the Sampler primitive. Previously, the measurements results were
expanded to more bits than actually measured which, for oracles with more than one qubit,
led to potential errors in the detection of the "good" quantum states for oracles.

Details and comments

Fixes the second bug report in #9384.
