Support gnome-42-2204-sdk for s390x and ppc64el architecture

[SiboVG]

Hi, I'm using the gnome extension to build my Java application, which works fine for armhf and amd64, but my application fails to build on s390x and ppc64el with the following error:

Failed to install or refresh snap 'gnome-42-2204-sdk'.
'gnome-42-2204-sdk' does not exist or is not available on channel 'latest/stable'.
Use `snap info gnome-42-2204-sdk` to get a list of channels the snap is available on.

What do you think I should do next? Is the gnome extension never going to work for those architectures?

Here's my snapcraft.yml file:

have and at least 2 to claim you and it is great that we are even more than his

gnome works on it's architecture if you have it installed so it's up to you to make sure that it also works on snap
