fix: increase default cpuRequest for askpass (#892)

The askpass sidecar is failing regularly on autopilot due to timing out
before the request can be served. This seems to be an issue of
insufficient CPU to serve the request within the 1s timeout. The new
value seems to pass consistently from experimentation. Intermediate
values of 20m and 30m were tested but still flaky.
