node 18 support + fix strapi v4 compatibility

[adipasquale]

hello, thanks for a great plugin !

I had to make a few tweaks in order for it to work on my new strapi v4 project though.

This builds upon a first tweak by @AndreasBaumgart (thank you) for node 18

I then adjusted a few things until it worked

• the github icon
• the strapi config in package json misses a kind and the name does not have the correct case
• a deprecated notfound import
• missing axios dependency
