Correct comment for array job max parallelism

[katrogan]

TL;DR

Update comment to indicate array job parallelism indicates max not min

Currently, the comment

flyteidl/protos/flyteidl/plugins/array_job.proto

Line 13 in b0c0831

int64 parallelism = 1;

implies that the parallelism field for array jobs is a min

however plugins code reads the field as a max:
