* website: update Tailscale VPN documentation
Replace use of breakglass with instructions to use interactive login.
This depends on https://github.com/tailscale/tailscale/pull/4117 being
merged.
Add mkfs into the example so that /perm filesystem is initialized.
Add instructions how to use auth-key for unattended device auth instead
of having to use browser interactively.
Append to tailscaled/flags.txt instead of overwriting.
Clarify and update the tsnet example. Add mention of TS_AUTHKEY
as alternative here too.
* website: set auth-key value on the same line for clarity
* website: require tailscale v1.22.1 to simplify instructions
Since tailscale.com v1.22.1 we do not need to set statedir and
tun=userspace-networking on gokrazy.
