IR send example in wiki no longer works

[ethagnawl]

The IR send example in the wiki no longer works using firmware version 1.3.4.

The current example causes the build to fail with the following error:

scons: Entering directory `/home/peter/.ufbt/current/scripts/ufbt'
CC /home/peter/projects/flipper/flipper-zero-tutorial-app/test_app.c
CDB /home/peter/projects/flipper/flipper-zero-tutorial-app/.vscode/compile_commands.json
/home/peter/projects/flipper/flipper-zero-tutorial-app/test_app.c:12:10: fatal error: infrared/infrared_signal.h: No such file or directory

| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

I think the entry should be modified to use the new (even simpler!) infrared_send function. (I was testing with Unleashed unlshd-082 but I believe they're API compatible as far as this feature goes.)

#include <infrared.h>
#include <infrared_transmit.h>
...
InfraredMessage message = {
    .protocol = InfraredProtocolSamsung32
    .address = 0x07,
    .command = 0x0F,
    .repeat = false,
};
infrared_send(&message, 1);
