fix Lumen Documentation Address

[SirousFakhri]

The Lumen Documentation Address referred to https://lumen.laravel.com/docs/10.x/main, which returns a 404 error.

Now Address refers to https://lumen.laravel.com/docs/master, The last version of the Lumen.

The lumen support should be removed by now.

https://lumen.laravel.com/docs/master#installation

Note: In the years since releasing Lumen, PHP has made a variety of wonderful performance improvements. For this reason, along with the availability of Laravel Octane, we no longer recommend that you begin new projects with Lumen. Instead, we recommend always beginning new projects with Laravel.
