Add Google Search Console to check keyword search volumes

[phuclh]

Add ability to check keyword search volumes from Google Search Console via this command:

php artisan keywords:check-search-volume https://tuikhoeconban.com --limit=1000

This will pull data from Google Search Console and check with our database. If we have that keyword in the database, then it will create or update the search volumes data in search_volumes table.

THIS IS GREAT! Thank you for creating a video showing me the code in action, @phuclh!

@drewroberts I still have one more question. Do we save the search volume data every range (month) or we only save the lastest range (month)?

[drewroberts]

For now, let's just save the latest range every month.

@pdbreen Could you fix the psalm errors on this PR?

[pdbreen]

@drewroberts psalm errors are fixed. Biggest issue was composer.json allowing php 7.3 but code was using php 7.4 syntax.

Thank you, @pdbreen!
