perf Documentation: Correct branch stack sampling call-stack option
The correct call-stack option for branch stack sampling should be "stack"
instead of "call_stack". Correct it.
$perf record -e instructions -j call_stack -- sleep 1
unknown branch filter call_stack, check man page
Usage: perf record [<options>] [<command>]
or: perf record [<options>] -- <command> [<options>]
-j, --branch-filter <branch filter mask>
branch stack filter modes
Fixes: 955f6def5590ce6c ("perf record: Add remaining branch filters: "no_cycles", "no_flags" & "hw_index"")
