[mohsenkhanpour]

Description

After recent update which enabled plugin option validation, gatsby-plugin-google-analytics throws with the following:

error Invalid plugin options for "gatsby-plugin-google-analytics":

- "cookieFlags" is not allowed
not finished load plugins - 9.797s

Although gatsby-plugin-google-analytics list cookieFlags as an option, it is not allowed after the latest update.

Steps to reproduce

1. Update gatsby and gatsby-plugin-google-analytics
2. Add cookieFlags option:

		{
			resolve: `gatsby-plugin-google-analytics`,
			options: {
				// replace "UA-XXXXXXXXX-X" with your own Tracking ID
				trackingId: 'UA-XXXXXXXXX-X',
				cookieFlags: 'Secure;SameSite=None',
			},
		},

Expected result

It should be accepted as a valid plugin option.

Actual result

It is not allowed and throws build process.

npmPackages:
    gatsby: 2.25.2 => 2.25.2 
    gatsby-plugin-google-analytics: ^2.4.0 => 2.4.0

@mxstbr Thanks for updating the schema, I just saw that some optional options were added.
However I took a look at https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby-plugin-google-analytics/src/gatsby-node.js and cookieFlags was not added to schema, please inspect.
