fn render should not format Kptfile and the fn config files used in a Kptfile

[mengqiy]

We need to verify if eval has this issue too.

This is by design. @phanimarupaka added the behavior recently.

@mengqiy why kpt render shouldn't format meta resources ?

[mengqiy]

There are 2 resources in this context:

• Kptfile
• fn-config.yaml files that are referenced by Kptfile.

I don't have a strong opinion about formatting Kptfile.
But IMO fn-config.yaml files should be invariants. Formatting them generates noise when looking at the diff of a package.
