Fix ANSI layout on yd60mq

[se-bastiaan]

Description

The layout that was defined in #309 contains a small mistake that this PR tries to fix. Before the ANSI layout defined used the 4,9 identifier for all the four modifiers in the bottom right. This means that enabling this layout does not allow you to edit all the modifiers and you are stuck with the Minila layout instead:

After this PR the keymap editor looks like this with all the keys correctly identified:

I also took the liberty of capitalising some of the used labels and accenting the Esc and Enter keys.
