Support Gatsby 5

[leonburman]

I'm hoping to upgrade to Gatsby v5 soon but this plugin doesn't currently support it.

@leonburman Gatsby v5 is not specified as a peer dependency here, but if you force install it it seems to work fine (at least I didn't notice any issues in my project)

The README states they don't intend to support it:

Loadable gregberge/loadable-components#718 and Gatsby v5 will require React 18. React 18 ships with React.lazy which performs the same code-splitting + SSR that we are accomplishing here. There are no plans to write compatibility for React 18 / Gatsby 5 with this plugin, so the migration path should be one to React.lazy. This should result in an overall simpler implementation, and should be considered a positive that this plugin will no longer be needed.
