Update levelshot (don't show broken shader remap)

[slipher]

The levelshot illustrates a bug with shader remap not working. The lighting bolts are not supposed to be visible except during a lighting strike. So take a new one. Thunder 1.3.6 with Unvanquished 0.55.4.

I tried to follow the webp compression instructions but the new file is bigger. Maybe the old one just used less space because it was dark?

Possible.

For reference, here are the viewpos I used for the stock maps:

antares -1013 -378 130 -47 -32
chasm -1866 -457 296 40 0
forlorn 2243 2217 348 125 -8
parpax 497 -2242 485 0 27
perseus 2592 -504 339 90 0
plat23 -229 2360 70 -59 -5
spacetracks 420 -1928 638 -31 -16
station 15 1168 -1240 114 124 -15
thunder 491 -808 -159 -65 -12
vega 1472 -1792 176 -180 0
yocto -2604 969 459 0 0

Anyway we may want to delay levelshot updates for after we switched to a colorspace-aware build.

We had this wrong levelshot for years, so we can live with it a bit more.
