Add code-checker to landing

[JustLuuuu]

Got this feedback more than once that it would be use-full for artists to have code-checker directly somewhere on landing. As we are now generative marketplace - this should be somewhere visible. Ideally, not in the footer because who would search that? The code-checker should be in a proper state and working, so there is no reason to "hide" it.

My suggestion: Euther directly on the main top menu. Or Add it to "create".

I don't mind any of the options, also open to any suggestions
