fix: cli: remove requirements in helptext

[rjan90]

Proposed Changes

The current lotus-worker run help text outputs the hw-requirements for some of the sealing-tasks.

lotus-worker run -h
NAME:
   lotus-worker run - Start lotus worker

USAGE:
   lotus-worker run [command options] [arguments...]

OPTIONS:
   --precommit1                  enable precommit1 (32G sectors: 1 core, 128GiB Memory) (default: true) [$LOTUS_WORKER_PRECOMMIT1]

A lot of the requirements in this text is wrong, as for example the PC1 requires 64GiB of memory, and might also use up to a single core complex (1 main core, 3 producer threads) if the FIL_PROOFS_USE_MULTICORE_SDR=1 enviroment variable is exported. I propose that we remove the the sealing hw-requirements from this helptext as there are a lot of nuances that is hard to communicate in the space available in the cli, and rather communicate them in the documentation https://lotus.filecoin.io/storage-providers/get-started/hardware-requirements/ - which has now been updated (only missing PRU/PRU2, but will update those hw-requirements on Monday):
