docs(readme): Windows SSH 'Permission denied (publickey)' passphrase gotcha

BulmAnanaBellerequested to merge
BulmAnanaBelle/gecko:docs/ssh-windows-troubleshooting into master

Adds a troubleshooting section to the README for Windows contributors.

Issue hit during setup: an SSH key generated in PowerShell with ssh-keygen -N '""' gets a passphrase equal to the two literal characters "" (not an empty passphrase). Non-interactive git/ssh then fail with Permission denied (publickey) even though the key is correctly registered — ssh -v is misleading, printing Server accepts key followed by Permission denied.

The new section provides diagnose / fix / verify steps.
