Easy frugal tutorial page updated

I have updated this page:

https://easyos.org/install/easy-frugal-installation.html

The main reason was to include information about kernel commandline parameters as an alternative to editing the BOOT_SPECS file in the initrd file.

While I was at it, also updated these:
