Not running on Gatsbyjs 4

[captainabap]

Hi @jxnblk ,

the Plugin gatsby-theme-mdx-deck is not working on the current version (4.14.0) of Gatsbyjs. Can you create an updated version?

Regards,
Jörg

mdx-deck is not really maintained anymore - probably you should not use it.

But if you want to try to upgrade to Gatsby v4 yourself, here's how we did it (actually, first upgraded to v3 - this was the biggest change - but upgrading to v4 was not as much work after this): #808

Gatsby v5 is now out, and we have not yet tried upgrading to this. We will probably switch off of mdx-deck first to another option such as MDXP.
