Deprecated warning message on composer install command

[peter279k]

When using the composer install command on this repository folder, it will present following warning message:

Deprecation warning: require-dev.json-schema/JSON-Schema-Test-Suite is invalid, it should not contain uppercase characters. Please use json-schema/json-schema-test-suite instead. Make sure you fix this as Composer 2.0 will error.

It seems that the json-schema/JSON-Schema-Test-Suite package name should be changed with lower-case.

It should. Please feel free to open a PR that makes this change.

I came across the same notice :) I also opened a PR #626 to backport it to 5.x.x. Thank you.
