Update legacy CLI to 2.31.0

Resolves the CLI output:

Warning: apollo update available from 2.30.2 to 2.31.0.

@ethansinjin Before I merge this, can you confirm that there are no changes locally to the API.swift for the StarWarsAPI when you build it with this change?

[ethansinjin]

@designatednerd Good catch! There are indeed two things I missed: updating the SHASUM and regenerating the API.swift files. I just did both, using the following:

shasum -a 256 ./apollo-v2.31.0-darwin-x64.tar.gz

# once in StarWarsAPI and once in UploadAPI
../../scripts/run-bundled-codegen.sh client:codegen --target=swift --includes "./*.graphql" --localSchemaFile="./schema.json" ./API.swift

# in GitHubAPI
../../scripts/run-bundled-codegen.sh client:codegen --target=swift --includes "./Queries/**/*.graphql" --localSchemaFile="./schema.docs.graphql" ./API.swift

ugh looking forward to getting rid of this stuff one day - unfortunately there's a few things I need to update on my end as well - I'm going to push some stuff to your branch to get it over the finish line
