fix: reset_team weights

[rflechtner]

Fixes an oversight in weights computation, where the number of currencies in a pool was not taken into account for the bonded-coins pallet's reset_team extrinsic.
Also updates the default weights accordingly.

Given that the run_benches_for_pallets.sh script no longer works, I've benchmarked this manually using the frame-omni-bencher. Double-check that I've done it right, given that it's my first time doing so.

Checklist:

• I have verified that the code works
  • No panics! (checked arithmetic ops, no indexing array[3] use get(3), ...)
• I have verified that the code is easy to understand
  • If not, I have left a well-balanced amount of inline comments
• I have left the code in a better state
• I have documented the changes (where applicable)
  • Either PR or Ticket to update the Docs
  • Link the PR/Ticket here

LGTM. I'm curious why this wasn't catchedduring the release. The node should not compile after running the benchmarks, no?

Yes indeed, but the benchmarks weren't actually run, that's why this wasn't caught.
