build-picker: PS5_VulkanTemplate b577e950, its current main

The picker was pinned to a6c32497, and tools/build-picker.sh requires the
template checkout to be at the pin, which it no longer is. b577e950 (on
GitHub) differs by rewritten commit ids, whose SDK and UI kit pins name the
same source trees (PS5_PayloadSDK 611893f = adc8dd7, PS5_VKHomebrewUI
2188642 = 4451c26, compared tree for tree), docs, and new-title.py's 1 GiB
flexible-memory request in a generated param.json, which the picker does not
use (it runs inside PPSA99169, whose param.json already asks for it). The
licence notices read the kit and SDK pins from the template's scripts, so
they follow.

Verified on the base PS5 (13.40), run-PPSA99169-204853: the picker generated
from b577e950, 300 frames, chose RetroArch, RetroArch quit after 600 frames,
back to the picker; picker test PASS (evidence/picker-template-pin; frame
klog/picker-204853/picker.png inspected). tools/verify.sh format and
evidence PASS (88 captures, 0 failed); build and integration wait for MAME's
rebuild.
