Example password hashes in iPXE guide don't work

[bwarden]

Describe the error/improvement to an existing document or image The password hashes in the iPXE installation guide have extraneous backslashes inserted prior to $ characters. As these fields are written as-is to /etc/shadow on the installed system, they are invalid password hashes, and will prevent login. https://github.com/clearlinux/clear-linux-documentation/blob/cc16a5efd4cda85c7df849c3f03a51ebd557a835/source/get-started/ipxe-install.rst#L288 https://github.com/clearlinux/clear-linux-documentation/blob/cc16a5efd4cda85c7df849c3f03a51ebd557a835/source/get-started/ipxe-install.rst#L293
