[Bug]: Grey hero variant - statistics logo is larger than the figma design, and unlinked

Expected behaviour / outcome

This is how it should look:

The logo should be 90px wide.

It should link to https://uksa.statisticsauthority.gov.uk/about-the-authority/uk-statistical-system/types-of-official-statistics/

List the steps necessary to reproduce the bug

Create a grey onsHero variant, and ensure that the option for officialStatisticsBadge is set to be true. Observer the image size, layout issues, and lack of link.
