Fix installation command with composer "[InvalidArgumentException] Could not find package gitscrum-community/laravel-gitscrum with stability stable."

Description

[InvalidArgumentException] Could not find package gitscrum-community/laravel-gitscrum with stability stable.

Motivation and context

When I try to create the project with composer, running the command in the documentation:
composer create-project gitscrum-community / laravel-gitscrum - stable = stable -keep-vcs
I get this error:
[InvalidArgumentException] Could not find package gitscrum-community / laravel-gitscrum with stability stable.

The correct command should be:
composer create-project gitscrum-community-edition/laravel-gitscrum --stability=stable --keep-vcs

How has this been tested?

Running this command, I don't get any errors:
composer create-project gitscrum-community-edition/laravel-gitscrum --stability=stable --keep-vcs
