add westeros houses example using google sheets

[shekharnwagh]

Description

This PR adds an example block for Google Sheets. Google Sheets like Airtable and unlike Shopify doesn't have a static schema for the data. So this example is just one example and the schema would be different for each Google Sheet. The example used here is a sheet containing the list of houses of Westeros with the columns as "Name", "Seat", "Region", "Words" and "Sigil". The 2 blocks added are:

• "Westeros House" to add a single house
• "Westeros Houses List" to add all houses

Testing

Google Sheets and Google API Access Setup

• To test this block, create a Google Sheet with above columns with the "Sigil" column having the URL of the sigil image.
• Create a project in Google Cloud Platform. resourcemanager.projects.create permission is needed to create a new project. Skip this step if you already have a project setup in your organization in Google Cloud Platform.
• Enable the Google Drive API for your project.
• Enable the Google Sheets API for your project.
• Create a service account for your project.
• Create a key for the service account. This will download a JSON key file. Keep this file safe as it will be used to authenticate the block.
• Convert the downloaded keys JSON to a JSON string, Base64 encode it and add it to the REMOTE_DATA_BLOCKS_EXAMPLE_GOOGLE_SHEETS_WESTEROS_HOUSES_ACCESS_TOKEN" key in the .wp-env.override.json file.

Trying out the block

• Start the local WordPress environment with npm run monolith
• Go to the WordPress admin dashboard at http://localhost:8888/wp-admin
• Create a new post and try adding the newly added "Westeros House" block to the post.
• You can also try adding the "Westeros Houses List" block to the post.

Cool stuff! Didn't test, but, code makes sense.

Tested, looks good. But I am concerned about all the fantasy content in these examples 😂

[shekharnwagh]

@chriszarate @mhsdef I am wondering if we should encrypt this token before writing to cache ? We do encrypt the data source config when we store it in options table, but that is persistent as opposed to this which has TTL of 50mins for now.

[mhsdef]

Ideally, yeah. We could do what we're doing with the DB option if there's a hook that fires in the cache set. I didn't see one, in brief perusing, but maybe I missed it.

Otherwise, could invoke our encryption code manually to handle.
