<p>Front-running (in the case you're referring to) is a concept related to on-chain trading, where miners order transactions to affect the exchange rates of smart contracts. Since bitcoin does not currently support smart contracts, ordering of transactions cannot affect the miner, as there is nothing to front-run.</p>

I agree with @Prayank's comment here, but think this answer overall is still more accurate: the reality is simply that Bitcoin simply doesn't have exchanges with on-chain order books like Ethereum has, so no money is to be made by reordering the execution of those.

on-chain bonding curves (aka trading with a liquidity pool as your counterparty) seem to be the primary target of frontrunning, moreso than order books I think
