fix: increase default memoryRequest for helm-sync (#895)

The helm-sync container is failing regularly on autopilot due to
OOMKill. Autopilot sets the limits equal to the requests, and the
current value is too low for all of the e2e tests to pass. Standard
allows bursting while autopilot does not. We may be able to revert this
increase after an upcoming change which will allow separate defaults for
standard and autopilot.
