Allow $schema in JSON schema

[jrmajor]

Adding {"$schema": "vendor/humbug/box/res/schema.json"} to the config file allows PhpStorm to provide completions. However, the $schema key is reported as not allowed.

Thank you very much @jrmajor!

This only works if you've installed Box via Composer in your local project, which you're generally not encouraged to do (or can't do, if you have conflicting dependencies).

What's the alternative if you've installed the Phar?

[theofidry]

I don't think you have one unfortunately. This would require to publish the schema from an easily downloadable place. Unless adding it to the release actually works, I don't see how it can be done.

Although maybe there is a way to point at the one contained in the PHAR?

"$schema": "https://raw.githubusercontent.com/box-project/box/main/res/schema.json" seems to work

Although it's not ideal, since the version is likely to get out of sync with the installed Box version.

I would suggest referencing the exact version instead of the main branch:

- "$schema": "https://raw.githubusercontent.com/box-project/box/main/res/schema.json"
+ "$schema": "https://raw.githubusercontent.com/box-project/box/4.2.0/res/schema.json"
