Missing WSL Guide and undocumented sudo behavior

[swittlich]

Description

The README references a guide at
https://raw.githubusercontent.com/swittlich/OneWare.CC-Toolchain/refs/heads/main/docs/WSL.md,
but the file does not exist.

The documentation should explicitly state that sudo must not require a password.
When openFPGAloader was not installed, no error appeared because sudo was waiting for a password prompt in the background.

Steps to Reproduce

1. Use WSL with the Olimex board
2. Follow the README instructions
3. Observe that the docs/WSL.md guide is missing
4. Run commands without openFPGAloader installed → no error shown, as sudo waits for password

Expected Behavior

• A valid docs/WSL.md guide is available
• Documentation clearly states that sudo must not require a password
• Missing tools like openFPGAloader produce a visible error
