Cleanup unused import in weak subjectivity calc

[clarenew]

Dropped the unused MAX_DEPOSITS import from assets/eip-6110/eth2_ws_calc.py, relying on the local constant that already provides the needed value. No behavioral changes expected.

@g11tech pls review

this PR as such seems correct as the MAX_DEPOSITS is being assigned in the compute fn itself, but may be authors want to use the import value and not the hardcoded one. so considering that it would be better if any of the authors can confirm/approve this PR or the other approach
