Composer signature in readme has uppercase characters

[mlambley]

Composer is giving me this warning:

Deprecation warning: require.PrintNode/printnode-php is invalid, it should not contain uppercase characters. Please use printnode/printnode-php instead. Make sure you fix this as Composer 2.0 will error.

I notice that you have it configured correctly in composer.json and therefore packagist as well. It's just a matter of updating your readme to use lowercase characters so that people who copy and paste will not make the same mistake that one of our devs made.

https://github.com/PrintNode/PrintNode-PHP/blob/master/README.md#install-via-composer

Is currently:

composer require PrintNode/printnode-php:dev-master

Needs to be:

composer require printnode/printnode-php:dev-master

Thanks
