doc: mptcp: net.mptcp.pm_type is deprecated

Browse Source 
The net.mptcp.pm_type sysctl knob has been deprecated in v6.15,
net.mptcp.path_manager should be used instead.

Adapt the section about path managers to suggest using the new sysctl
knob instead of the deprecated one.

Fixes: 595c26d122 ("mptcp: sysctl: set path manager by name")
