* Fix 1.21 regression: GET_32G_MAX_CONCURRENT + mixed prepared/executing leads to stuck scheduler
If you have 12 GET tasks and GET_32G_MAX_CONCURRENT=1, sealing jobs will only show assigned tasks for GET of the miner
and is stuck.
I believe this to be a regression of 1.21 unifying the counters, in the case of GETs where PrepType and TaskType
both being seal/v0/fetch leading to a state where tasks are blocked since already counted towards the limit.
* itests: Repro issue from PR #10633
* make counters int (non-working)
* fix: worker sched: Send taskDone notifs after tasks are done
* itests: Make TestPledgeMaxConcurrentGet actually reproduce the issue
* make the linter happy
