Install WPGraphQL and WPGraphiQL plugins in WordPress using the command line

In order to use WordPress with the Jamstack, we want to be able to read data from WordPress using GraphQL. By adding WPGraphQL, we enable a powerful GraphQL API for our WordPress sites, and WPGraphiQL gives us an in-dashboard interface for testing GraphQL queries.

Because these are developer-focused plugins, they’re not available the standard plugin library, so we need to install them from GitHub using the CLI.
