[BUG] Commands no longer overwrite default Laravel Scout commands

[serpentblade]

Describe the bug
A recent change in Laravel Scout v8.6.1 moved commands to be registered during boot():
laravel/scout#453

This causes the default scout:import to be used rather than this service, regardless of the order of ServiceProviders.

To Reproduce
Steps to reproduce the behavior:

1. Upgrade to Laravel Scout v8.6.1
2. Run command php artisan scout:import 'App\YourModel'
3. Artisan will run the default import command instead of this package's command

Expected behavior
This service should override the scout:import command

Additional context
I believe a simple fix should be move to move the call to registerCommands() inside of boot() instead of register(), however I don't know what the impact would be to versions of Scout prior to v8.6.1. My guess is it would be okay as boot() always occurs after register() so it would still properly override. Some testing against different versions of v8 may be required or upping the minimum version dependency to laravel\scout ^8.6.1.

Version
Versions of Laravel, Scout, and the package.
