This PR removes a Google Ads API file vendor/googleads/google-ads-php/scripts/print_php_information.php that prints the php information using phpinfo().

There is already a script bin/cleanup-vendor-files.sh that removes the unneeded vendor files, adding one more removal there.

The file wasn't used anywhere in the code, so it's safe to remove it after composer install.

I also checked other files under vendor/ folder and confirmed no one is also calling phpinfo().

What does vendor/googleads/google-ads-php/scripts/print_php_information.php do?

It's mainly used in googleads/google-ads-php repo when anyone creates a bug report issue, they recommend the issue opener attaches the output of that script.

Ref: googleads/google-ads-php#466
