Improve USB Flashing steps

[hpsaturn]

Summary

The current version needs extra steps to change the USB permissions into the Docker container. Will be nice fix that. I added the internal user to dialup group and also I did some tests with special commands on docker run to have permissions into the device. But nothing. If you know how to fix that, please do a PR.

Details

Without the current flashing steps, we would have:

Project build complete. To flash, run this command:
/app/build/.espressif/python_env/idf5.1_py3.10_env/bin/python ../esp-idf/components/esptool_py/esptool/esptool.py -p (PORT) -b 460800 --before default_reset --after hard_reset --chip esp32s3  write_flash --flash_mode dio --flash_size 8MB --flash_freq 80m 0x0 build/bootloader/bootloader.bin 0x8000 build/partition_table/partition-table.bin 0x10000 build/network_adapter.bin
or run 'idf.py -p (PORT) flash'
+ read -p 'ready to flash... press enter'
ready to flash... press enter
+ idf.py -b 2000000 flash
Executing action: flash
Serial port /dev/ttyACM0
/dev/ttyACM0 failed to connect: Could not open /dev/ttyACM0, the port is busy or doesn't exist.
([Errno 13] could not open port /dev/ttyACM0: [Errno 13] Permission denied: '/dev/ttyACM0')

Hint: Try to add user into dialout group: sudo usermod -a -G dialout $USER

No serial ports found. Connect a device, or use '-p PORT' option to set a specific port.
+ read -p 'failure... press enter to try again

Seems that the Docker people fixed this issue on Docker level.
