Also fix the typo in the function name

this function does not seem to get called anywhere anyway

Since 2019, this method is whispering "master... please... kill me..."

So, please respect their wish, and kill it with maximum violence.

kill it

This stuff was introduced in rPf7e8fa0764fe7bd2546442cccbb6ec447b0ea8e2 so I initially thought the consumers were meant to be potential external editor code but I might be wrong because they are final protected. Indeed newRequiredTransactionError and newInvalidTransactionError are not called anywhere within Phorge itself, so if you confirm I am fine with removing both.

@valerio.bozzolan Any thoughts/opinion regarding my last comment? :) TIA

Feel free to kill this method violently 🗡 since as you said this is protected (no external usages) + final (no overrides) and visibly broken since 5 years

(Fun fact, to type the dagger emojii I tiped :D since I always type :D obtaining a dagger by mistake. Now it's a feature. asd - T15285)
