rover dev --graph-ref doesn't override federation_version from local supergraph.yaml

[michael-watson]

Description

When using the --graph-ref option for rover dev, the federation_version used for composition defaults to what is defined in GraphOS and ignores the value defined in your local supergraph.yaml

Steps to reproduce

1. Start with any new graph in GraphOS, you just need 1 subgraph
2. Create a new simple schema.graphql file locally:

type Query {
  helloWorld: String
}

3. Create a supergraph.yaml file locally:

federation_version: =2.10.0-alpha.0
subgraphs:
  test:
    routing_url: http://localhost 
    schema:
      file: schema.graphql

4. run rover dev command

APOLLO_KEY={API_KEY} rover dev --graph-ref graph@ref --supergraph-config supergraph.yaml

5. Composition value used in rover dev output will default to the value set in GraphOS and ignored the alpha version

Expected result

rover dev --graph-ref should always use the federation_version defined in the local supergraph config file

Actual result

rover dev --graph-ref ignores the federation_version value defined in the local supergraph config file
