Select the VM arch based on the Ansible architecture value

[Nuttymoon]

Currently, the arch used to install VMs is hardcoded to amd64:

ansible-avalanche-collection/roles/node/vars/main.yml

Line 28 in 212a64e

avalanchego_vm_binary_filename: "{{ vm_name }}_{{ vm_version }}_linux_amd64.tar.gz"

We should use a similar mechanism than for AvalancheGo and Ash CLI:

ansible-avalanche-collection/roles/node/vars/main.yml

Line 7 in 212a64e

avalanchego_binary_name: "avalanchego-linux-{{ avalanchego_binary_arch }}-v{{ avalanchego_version }}.tar.gz"

ansible-avalanche-collection/roles/node/tasks/install-avalanchego.yml

Lines 53 to 55 in 212a64e

	- name: Set avalanchego_binary_arch according to ansible_architecture
	set_fact:
	avalanchego_binary_arch: "{{ 'amd64' if ansible_architecture == 'x86_64' else 'arm64' if ansible_architecture == 'aarch64' else avalanchego_binary_arch }}"
