docs: the boot log confirms the vgamepad failure verbatim

'skip_intro.sh: line 44: vgamepad: command not found' right after 'movie -> skip
A'. Every '-> skip A' and 'TITLE -> A' this harness has printed pressed nothing,
which is also why the intro movie ran to 434s: it was never skipped.

+The boot log states it outright, which is the only reason it was caught:

+movie (rmse 1662) at 434s -> skip A
+tools/re-capture/skip_intro.sh: line 44: vgamepad: command not found

+Every "-> skip A" and every "TITLE -> A" this harness has ever printed pressed
+nothing. Note the timing too: the movie ran to **434 s** because it was never
+skipped, which is most of why a boot takes seven minutes here.

 That second bug looked like it would explain the standing "Ⓐ at the title works
 about half the time" note. **It does not.** See below.
