[PATCH liburing v2 4/7] man: Add `io_uring_enter2()` function signature

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

From: Ammar Faizi <ammarfaizi2@gnuweeb.org>

Since kernel 5.11, liburing has io_uring_enter2() wrapper which behaves
just like the io_uring_enter(), but with an extra argument for
`IORING_ENTER_EXT_ARG` case. Add this function signature to the
synopsis part. Also, change the function name in "kernel 5.11" part to
io_uring_enter2().
