docs: Fix dual-BOOM-Rocket-Hwacha documentation

Browse Source 
The docs indicate that this should be a dual-BOOM and single-Rocket
config, with the Hwacha attached to the Rocket. However, the
'LargeBoomAndHwachaRocketConfig' config only has a single Rocket core.
Added the 'DualLargeBoomAndHwachaRocketConfig' config to accurately
reflect what's stated in the docs.

Additionally, this fixes hart numbering to place the Hwacha accelerator
on the Rocket core rather than on the BOOM core.
