Convention: quilkin.yaml file

[XAMPPRocky]

While working on the project I usually have a yaml that I use to develop on it, and it's slightly annoying to have to keep git from checking it in. So I would like to propose that we use quilkin.yaml as the default filename for quilkin configuration, and add quilkin.yaml to the .gitignore. We could also change --filename to look at quilkin.yaml by default.

This sounds reasonable to me!

This is the only https://github.com/googleforgames/quilkin/blob/main/build/release/quilkin.yaml I could find in the repo currently.

But otherwise, no objection here.

We can still have quilkin.yaml's in repository, I think just reserving the top level is the most important in terms of development.

👍🏻 just highlighting is just in case it gets caught up in an ignore rule accidentally.
