setup: update web3 to v5

A clean-room install of `[.dev]` produces a `pip` error:

    ERROR: eth-tester 0.2.0b3 has requirement eth-abi<3.0.0,>=2.0.0b4, but you'll have eth-abi 1.3.0 which is incompatible.

The older `eth-abi` is pulled in via `web3` v4. To resolve this,
v5 is installed.

SQUASHED:

setup: update websockets to actual dependency number.

`web3` pulls in `>=8.1.0,<9`, so do the same to stay on the safe side.

`pip install -e .[dev]` would actually install v8.1.0 anyway.
