## PR-Codex overview
This PR focuses on improving support for Layer 2 (L2) functionality
within the Celo ecosystem, including deprecating certain methods and
enhancing compatibility for L2 operations.

### Detailed summary
- Updated `rewards:show` command description to indicate removal in L2.
- Added backward compatibility for methods using epoch's block numbers
in `@celo/contractkit`.
- Deprecated methods in `DowntimeSlasher`, `Governance`, and
`Validators` for L2 support.
- Adjusted tests to accommodate L2 changes, including new functionality
for fetching epoch block information.
- Enhanced coverage for `show` and `show-l2` commands with additional
tests.
