doc: mptcp: net.mptcp.pm_type is deprecated 



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.

Path managers are controlled by the ``net.mptcp.pm_type`` sysctl knob -- see

mptcp-sysctl.rst. There are two types: the in-kernel one (type ``0``) where the

same rules are applied for all the connections (see: ``ip mptcp``) ; and the

userspace one (type ``1``), controlled by a userspace daemon (i.e. `mptcpd

connection. The path managers can be controlled via a Netlink API; see
