[PATCH] docs: cgroup-v2: mark memory.pressure and io.pressure as read-write

[PATCH] docs: cgroup-v2: mark memory.pressure and io.pressure as read-write

[Tao Cui]

From: Tao Cui <cuitao@kylinos.cn>

The cgroup-v2 documentation describes memory.pressure and io.pressure as
"read-only nested-keyed file", but both files accept trigger writes
(cgroup_memory_pressure_write / cgroup_io_pressure_write) and are therefore
read-write. cpu.pressure and irq.pressure are already documented as
read-write, so this also resolves an internal inconsistency.
