Increase timeout of release phases

Increase the timeout of release builds from five minutes to ten since
I'm seeing the latest attempt on macOS time out [1].

Also, rename the configuration file from `ci.yml` to `ci.yaml` for the
additional letter in fuzzy file finds and to be more standard with my
other projects.
