docs: update installation instructions for 1.54.0

Closes #19

Note: Not all artifacts are available for the download now.

I've followed the instructions on this PR (for M1), and managed to build successfully without getting the #3 issue.

When flashing to the device, I however get the error:

Serial port /dev/cu.usbserial-1130
Connecting....

A fatal error occurred: This chip is ESP32-C3 not ESP32. Wrong --chip argument?
CMake Error at run_serial_tool.cmake:56 (message):
  /Users/nevilledipale/.espressif/python_env/idf4.4_py3.9_env/bin/python
  /Users/nevilledipale/esp/esp-idf/components/esptool_py/esptool/esptool.py
  --chip esp32 failed

I had set up esp-idf with esp32-c3, so I don't know what I'm doing wrong.

Given that esp32-c3 doesn't use Xtensa (at least that's my understanding), does it mean that I'm building incorrectly for esp32 through these instructions?

[igrr]

The instructions indeed produce a build for esp32, by default. If you need to build for esp32-c3, please run idf.py set-target esp32c3 before running idf.py build.

@nevi-me Thank you for pointing out the problem. Selection of the architecture was not obvious from the documentation. I've updated all documents, so that they contain selection of the architecture and also the reference to C3 installation instructions.

@MabezDev Please review updated instructions.

Thanks @georgik. Am I correct in saying that for esp32-c3, I then don't need to follow this process?

If so, when I follow the C3 instructions in the main branch, I get the below just like with #3

error[E0432]: unresolved import `core::sync::atomic::AtomicUsize`

@nevi-me That's correct. C3 has limitation on Atomics. Please follow the discussion in #3 There is active work on resolving this issue.
