Ensure all yaml checksums are quoted

[whaught]

Proposed Changes

• If you win the hashcode lottery and get a checksum that is all numeric, this parses as an int instead of a string and fails.
  • Quotes ensure proper parsing
  • This was mysterious and confusing in: Move PodSpec DryRun to enabled by default #8582

You probably want to actually change the generator in pkg to emit this as such (though I think it's already a sting node).

Yeah here: https://github.com/knative/pkg/tree/master/configmap/hash-gen

For pkg: knative/pkg#1472

Abandon this one? :)

Abandon this one? :)

These aren't dynamically generated by pkg or anything. I think we still want to fix the formatting in the dependant repos so this doesn't proliferate from copy/pasting

[vagababov]

did you generate those with update-codegen ?

[dprotaso]

yeah update codgen updates the checksums

[vagababov]

yeah update codgen updates the checksums

I know :) I wanted to make sure here it's done this way vs original manual quotations
