docs: Fix a few typos (#2274)

* docs: Fix a few typos

There are small typos in:
- redis/cluster.py
- redis/commands/core.py
- redis/ocsp.py
- tests/test_cluster.py

Fixes:
- Should read `validity` rather than `valididy`.
- Should read `reinitialize` rather than `reinitilize`.
- Should read `farthest` rather than `farest`.
- Should read `commands` rather than `comamnds`.

* Update core.py
