chore: remove ARM support

Browse Source 
Building/testing for ARM does not happen often - the only runtime environment is Raspberry PI, which supports ARM64 - and complicates support for a ton of features. Aside from that, CI runs are much longer for ARM Dokku images, often reaching 15-20 minutes or just timing out completely.

Rather than support an architecture that doesn't have much usage by maintainers and has a lot of maintenance burden, we're removing the platform.

By default, the builder-herokuish plugin is not enabled for non-amd64 platforms, and attempting to use it is blocked. This is because the majority of buildpacks are not cross-platform compatible, and thus building apps will either be considerably slower - due to emulating the amd64 platform - or won't work - due to building amd64 packages on arm/arm64 platforms.

To force-enable herokuish on non-amd64 platforms, the `allowed` property can be set via `builder-herokuish:set`. The default value depends on the host platform architecture (`true` on amd64, `false` otherwise).
