Automatic merge from submit-queue

Increase default value of apps/v1beta2 DeploymentSpec.RevisionHistoryLimit to 10

**What this PR does / why we need it**:

All controllers that use the `RevisionHistoryLimit` field have a default value of 10 for the field, except for `Deployment`, which has a default of 2. We should increase it to 10 for consistency on its default value across controllers.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #49913
