Snap installs from i386 arduino-cli tarball on aarch64

[NetworkAndSoftware]

Hello.

Ubuntu 22.04 LTS on Raspberry Pi 4.

$ uname -i -m
aarch64 aarch64

$ sudo apt-get install arduino-cli
arduino-cli 0.29.0 from manchoz installed
$ arduino-cli 
/snap/arduino-cli/33/snap/command-chain/snapcraft-runner: 4: exec: /snap/arduino-cli/33/usr/bin/arduino-cli: Exec format error

A little experimentation shows that this the arduino-cli that has been installed is the i386 one:

$ wget -q https://github.com/arduino/arduino-cli/releases/download/0.29.0/arduino-cli_0.29.0_Linux_32bit.tar.gz
$ tar -xzf arduino-cli_0.29.0_Linux_32bit.tar.gz 
$ diff -s arduino-cli /snap/arduino-cli/33/usr/bin/arduino-cli
Files arduino-cli and /snap/arduino-cli/33/usr/bin/arduino-cli are identical

The arduino-cli from https://github.com/arduino/arduino-cli/releases/download/0.29.0/arduino-cli_0.29.0_Linux_ARM64.tar.gz runs flawlessly.

Even sudo SNAP_ARCH=aarch64 snap install arduino-cli installs the incorrect version.

I ran into this issue w/ i386 32bit version on my Linux server. I tried setting SNAP_ARCH to amd64 but it still installs 32-bit version.
