DEV: Remove cache option from ajax() (#13142)

1. It defaults to `cache: true` already
2. Setting it to `false` for non-GET request doesn't do anything
3. We were correcting `cache: false` GET requests to use `cache: true`

…so setting it to anything at all, for any type of request doesn't make sense (anymore)
