Update controller map image

[pktiuk]

This is how it looks now:

It would be good to use some SVG image (or maybe something with better defined edges), because this image doesn't look very good with dark themes. (and is a bit outdated - missing share button)

In this case we should Use a bit different picture this time.
As @Igetin mentioned in #307 (comment)

@pktiuk Can you reopen this issue? SDL does, in fact, support the share button of the controller. The "not recognized by SDL" error message was a red herring, which is caused by the Linux kernel driver translating the share button press into a (non-joypad) key press, resulting in SDL showing both the button press and the error for the unrecognized key press.

AntiMicroX's log output was also lacking because of the kernel driver not directly supporting the button.

As discovered here, AntiMicroX does not recognize the share button because it is not handling the SDL_CONTROLLER_BUTTON_MISC1 button type.

The SDL mapping string looks like this when created with their mapping tool:

050000005e040000130b000007050000,Xbox Series X Controller,platform:Linux,a:b0,b:b1,x:b3,y:b4,back:b10,guide:b12,start:b11,leftstick:b13,rightstick:b14,leftshoulder:b6,rightshoulder:b7,dpup:h0.1,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,misc1:b15,leftx:a0,lefty:a1,rightx:a2,righty:a3,lefttrigger:a5,righttrigger:+a4,

The misc1:b15 part there is the mapping for SDL_CONTROLLER_BUTTON_MISC1.

Another closely related thing: I think the controller mapping dialog of AntiMicroX should be updated to support this additional button as well. The button should be shown in the mapping list and in the controller image.

Here is how SDL's official mapping tool displays it:

Of course, I can make this into a separate issue, if needed.

Feel free to use the following SVG, on which I spent 5 minutes. :P

Based on this original image.

Thank you, this will come in handy for sure.
