Fix missing f-prefix in exponential histogram max_size error messages

The continuation strings of the two ValueError messages in
_ExponentialBucketHistogramAggregation lacked the f prefix, so the
literal text {self._min_max_size} / {self._max_max_size} was printed
instead of the actual limits (2 / 16384).
