Add setup instructions for Linux

[mukrop]

Currently, all instructions presume Windows machines. Many (most?) of the people to who Logics get via Red Hat will be Linux users. I see adding Linux alternatives to the instructions quite low-cost with high added value.

My experience (from setting up everything on Fedora 38):

• Setting up VS Code is pretty standardized (download package from the website or a distro version).
• Similarly with Python and git.
• The driver does not need to be installed, it's a part of the Linux kernel since v2.6.12 (more details)
• PlatformIO installation is the same.
• However, udev.rules need to be installed for PlatformIO (official manual), otherwise the device cannot be seen in PIO's "Devices" view (this can be mentioned as a diagnostic).
• I would also add the final remark (for all OSes) regarding uploading and running the program: What USB port to use, that the program should run automatically after being uploaded to the board, and maybe even a warning that some USB cables are charging-only (a dumb information, true, but it took me a while to realize this was one of the errors I was doing).
