Install troubleshooting with ssh

Those instructions will be useful to refer users to from forum or support tickets.

I think it would be useful to also explain:

1. When the SSH server becomes available
2. How to connect (which user, which hostname/IP - that's obvious but it doesn't hurt being explicit, which password - same)

The wording could be a bit more natural, something like that:

While the console access method described above may be sufficient for simple issues, collecting full logs (install logs, kernel logs, etc.) often requires copying large amounts of data, which is impractical without direct file access.

To enable SSH/SCP access during installation, you can use the Linux kernel command line to:

1. Activate the network
2. Enable the sshd service
3. Set a root password of your choice

For the most common case (setting up the network via DHCP), add the following parameter to the Linux boot section:

I suggest this wording:

You can also use the network_config parameter (which defaults to dhcp) to define an alternative network setup. Here’s how it works:

• Replace the capitalized values with your own settings. Square brackets ([]) indicate optional parameters.
  network_config=dhcp[:vlan=VLAN]
network_config=static:ip=IP;netmask=NETMASK[;gateway=GW][;dns=DNS1[,DNS2]][;domain=DOMAIN][;vlan=VLAN]

Feel free to use Docusaurus' "Note" element:

:::note
You can specify an interface name such as `eth1` instead of `all` if necessary, which can be useful when you need to setup a static IP address.
