Lead hold locators are offset

The locators used for positioning the lead hold position were broken in the first 1.21.90 preview, as seen in MCPE-217604.

Although the latest preview listed that issue as fixed, all it did was manually move the locators in most models in an attempt to correct for the offset, but the underlying issue is still affecting the game.

MCPE-219598 serves as an example that is still visible in the game.
