Nitpick, is "GHERKIN" all caps the actual name? I've always seen it as "Gherkin".

It's a fair cop, renamed to Gherkin

If we do keep this transform, it should be in the shape of the Gherkin (3x10?) not 5x6.

I don't believe this is necessary as this keyboard is a perfect grid. Similar to it missing in the planck seen here: https://github.com/zmkfirmware/zmk/blob/main/app/boards/arm/planck/planck_rev6.dts#L20

It doesn't hurt to include this I suppose, but it's also superfluous.

I don't actually own a gherkin to test on, so i'm too afraid to delete this because gherkin does have a git of a funny matrix, but if you're confident i can remove it.

I've added references to the other files.
