feat: update registry coordinator for new createOperatorSets

[ypatil12]

Motivation:

As part of Layr-Labs/eigenlayer-contracts#1645, we are adding a new createOperatorSets function that passes in the slasher address upon creation of an operatorSet. Although the old function is not being deprecated, we are updating the RegistryCoordinator in order to be compatible with this release.

Modifications:

• Update createSlashableStakeQuorum to take in a slasher address
• Update all tests
• Update solc version in foundry.toml to 0.8.29, matching Core

Result:

Compatible with updated AllocationManager interface
