Without this entry, lava buckets get the vanilla bucket-burn fallback
of 20000 ticks each — which made lava more powerful than refined
TFMG kerosene/naphtha despite being free and trivially obtainable.
Setting lava to 8000 ticks matches crude_oil exactly: both are the
raw entry-tier fuels you can scoop without any infrastructure, and
the player has to commit to a refining setup to unlock the higher
tiers.
Solid fuels (coal, charcoal, blaze rods, etc.) continue to work via
realisticTrains' chest/barrel pathway -- no datapack entry needed.
