fix: bump apollo-server-express and graphql-yoga

Removes [apollo-server-express](https://github.com/apollographql/apollo-server/tree/HEAD/packages/apollo-server-express). It's no longer used after updating ancestor dependency [graphql-yoga](https://github.com/graphql-hive/graphql-yoga/tree/HEAD/packages/graphql-yoga). These dependencies need to be updated together.


Removes `apollo-server-express`

Updates `graphql-yoga` from 1.18.3 to 5.18.0
