ci+aarch64: build pmm-aarch64 binary + linux-aarch64 .pdm; install.sh picks arch asset

- release.yml matrix adds linux-aarch64 (cc aarch64-linux-gnu-gcc), builds
  out/pmm-aarch64, and produces pmm-<ver>-linux-aarch64.pdm (pure-tar pdm) when
  that binary exists; amd64/windows packages unchanged.
- web/install.sh: download pmm (amd64) vs pmm-aarch64 (arm64) per arch, dropping
  the 'only amd64 provided' warning.
