fix(android): drop the manifest installArgs the type no longer declares

#2619 copied the snapshot helper manifest fixture after #2618 deleted
`installArgs` from AndroidSnapshotHelperManifest, so the new fixture failed
typecheck on main: the field is parsed by no one and the leniency case is
already covered in snapshot-helper.test.ts.

Repair for the breakage on main (2cafab3), unrelated to the settings
vocabulary refactor it blocks here.
