Updates Google copy and assets to reflect new name

[deandre]

This change updates copy and assets to reflect Google Apps' new name, Google Workspace. This change was necessary to align with doc updates in dnsimple/dnsimple-support@4437ea2.

I think these changes are all that's necessary, but please lemme know if there's anything else to be done.

@deandre thanks for this PR. Unfortunately, we cannot rename services at the moment. There are 2 ways to proceed when a change like this is needed:

• Keep the folder in place, and update the relevant fields along with the logo. We do this for rebrandings, so it would apply here.
• Deprecate the service and create a new one. This would make sense if the DNS and the branding is completely different. Which is not the case here.

So you'll need to keep the google-apps folder in place. Here's what you can do:

1. Inside the config.json, you can rename the following fields:

• label

• description

  The name will still have to be google-apps for now.

2. You can update the instructions.md, the readme.md, and the logo.png.

I think this is a constraint that we can clarify in the readme of this repository. I'll be happy to do this.
