Dependency resolution fails using Node 18 LTS

[leifwritescode]

Using the instructions in the readme, it is not possible to initialise this starter using gatsby new. The following errors are seen.

npm ERR! code ERESOLVE

Switching to Node v14 latest and using gatsby-cli@4.13.0 gets you past the gatsby new stage, but then gatsby develop fails when pointed at a Ghost v5 CMS. The absence of prerequisite information makes this starter very difficult to use.
