Can't pass through presubmit with policy_templates.json

[igo...@chromium.org]

Have there been any recent changes in presubmit scripts?

I'm trying to commit the policy_templates.json file and get an error. Following is the changes:

--- a/components/policy/resources/policy_templates.json

+++ b/components/policy/resources/policy_templates.json

       'features': {

         'dynamic_refresh': True,

       },

+      'deprecated': True,

       'example_value': 1,

And following is the error:

I also tried to undo the changes, save the file and run the presubmit_support.py locally. Got the same error.
