hi i have a question about pulumi.yaml files, as there are multiple i kinda see the intention pulumi.dev.yaml for dev env pulumi.prod.yaml for prod env but what is the prupose of pulumi.yaml? Contents of pulumi.yaml (auto generated)

name: modules

runtime: nodejs

description: A minimal AWS TypeScript Pulumi program

vs pulumi.dev.yaml

config:

aws:region: eu-west-1

pulumi.yaml

holds the project information while

pulumi.*.yaml

holds the stack(instance of the project) information

Yup, some more details about

Pulumi.yaml

at https://www.pulumi.com/docs/reference/pulumi-yaml/ The Pulumi.*.yaml files just have config values for the given stack.
