Subject: [PATCH] fix: pin BizHawk on the 2.11.1 it ships

The profile was pinned at 427556b5 (2.11) while the platform transcribes 2.11.1. In 2.11.1 FirmwareDatabase.cs rates one option per slot Ideal (MCD_eu_100, MCD_jp_100p, SCD_m1_us_110, SMS v1.3, gbaNormal and others), adds TI83_110.rom and a doom2.wad slot (DSDA.cs:85-99), and resizes the TI-83 Plus ROMs. The Ideal option of each slot is the required one, refs into the 12 changed files are remapped, and the 40 firmware files 2.11.1 names that the collection lacked are collected, each sha1-verified (LA_us_102.bin matches No-Intro [BIOS] LaserActive (USA) (v1.02)).
