New post_install.sh script that works for Nano Every

[seaxwi]

This PR adds a post_install.sh script consistent with the one for ArduinoCore-mbed. Using the same path for the script will simplify troubleshooting instructions. The new script also includes udev rules for Nano Every,

Changes in this PR

• Replace scripts/create_udev_rule with post_install.sh (based on post_install.sh)
• Use a simiilar structure (more readable)
• Add udev rules for Nano Every
• Change the name of the created file from 99-arduino-uno-wifi-rev2.rules to 60-arduino-megaAVR.rules.

Tests

Before running post_install.sh (missing udev rules)

After running post_install.sh (new udev rules added)

UNO WiFi Rev2 ✅

Upload successful, although on my system a "spurious" avrdude: usbdev_open(): WARNING: failed to set configuration 1: Device or resource busy warning is thrown. However, I get the same result with the rules set by scripts/create_udev_rule, so I believe its occurence is unaffected by this PR.

Nano Every ✅

Upload successful.
