docs: tie aps3e 2.43 to main4, not its tag

The 2.43 tag sits on main2 (b5ae1af, changelog ending at 1.38) while
the 2.43.apk asset carries main4's changelog and RPCS3 20071-1f080485.
The two branches share merge base d4622157. The pin c6ca182 already
names the released tree.

   Source drops land on successive branches, not on the default one. Release 2.43
-  of 2026-10-05 is the commit titled 2.43 at the head of main4. The lightweight
-  tags 2.39 to 2.43 all sit on the head of main2, the default branch, an April
-  tree that predates every one of those releases and whose generated
-  git-version.h was never filled in. main4 is the tree read here. No versionName is usable either:
-  the only gradle file committed is app/build.gradle.bak, which carries the
-  placeholder 1.19a and is renamed and completed with the signing block at build
-  time.
