Update path to /path/to/vendor/bin under Install > Execution

[gitressa]

Describe the bug

The current documentation is using a wrong path for the single Drupal codebase tip.

2. Execution. Change your working directory to your project root, and call Drush via vendor/bin/drush. To make this easier, append ./vendor/bin to the end of your $PATH; this allows you to call Drush via drush once your working directory is set. If you only have only one Drupal codebase on your system, you may put /path/to/vendor/bin/drush in your $PATH; if you do this, then it is not necessary to set your working directory before calling Drush.

From https://www.drush.org/latest/install/

To Reproduce

1. Add /path/to/vendor/bin/drush to $PATH
2. Run drush from any folder and fail

Expected behavior

Allow running drush from any folder.

Workaround

Add /path/to/vendor/bin to $PATH.
