PPM and ARM images for Linux

[krlmlr]

I looked into it but gave up -- too many things that need changing, I presume:

• ppm_has_binaries() returns TRUE ✅
• ppm_platforms() gets a new column arch ✅
  • the "arm64" values returned by PPM are translated to "aarch64" 🤙
• ppm_binary_url() uses the new format "https://p3m.dev/cran/latest/bin/linux/noble-4.5/aarch64" instead of "https://p3m.dev/cran/latest/bin/linux/4.5-noble" 🤷‍♂️
• anything else?

I have a Docker image that can be used in a devcontainer setup with R and all dependencies installed, multi-platform: https://github.com/cynkra/docker-images/pkgs/container/docker-images%2Fubuntu24-rig-rrel-dc-dt-pkgcache .

Automatic installation of binary packages on Linux ARM via pak works now for me.

Still need to fix

• ppm_has_binaries()
• ppm_platforms()

I think ppm_binary_url() is fine, the old URL works as long as you set the proper user agent header.
