Link to docusaurus in footer of docs.nocodb.com

[brandondrew]

If you navigate to https://docs.nocodb.com/table-details/table-details-overview/#ruby (or probably any page on that site, but that's the one where I found it) and scroll down to the footer and mouse over the link to GitHub, you'll see that the link takes you to https://github.com/facebook/docusaurus instead of anything related to NocoDB. I'm guessing that Docusaurus was used for the docs site, and the default URL was never changed.
