Require project autoloader in wp-cli.yml

[ethanclevenger91]

If you're using the global WP-CLI, it won't include the project's Composer autoloader until WordPress itself loads and Bedrock's own code to include the autoloader happens. This means that if you require third-party WP-CLI commands in a project and attempt to run them via a global copy of WP-CLI, those commands will not load before WordPress, even if they should (via @when before_wp_load).

Use case:

• Have WP-CLI available globally via their install instructions
• Create a Bedrock project
• composer require aaemnnosttv/wp-cli-dotenv-command
• Run wp help
• See dotenv under available commands
• Run wp dotenv init --template=.env.example --with-salts (this command is configured to be available before_wp_load)

Expected behavior: Create .env file from template

Actual behavior: Error because database could not be reached

Requiring the local autoloader as part of WP-CLI's configuration makes commands available when they're supposed to be available, regardless of which instance of WP-CLI you're using.
