Restrictive typing on evalsha keys_and_args argument

[icgood]

Describe the bug

The Redis eval method uses *keys_and_args: EncodableT to type variable arguments, but the evalsha method uses *keys_and_args: str. It should allow all the encodable types as arguments.

To Reproduce

In aioredis 2.0.0:

await redis.evalsha(sha, num_keys, b'foo', 'bar')

Run mypy and observe the following error:

Argument 3 to "evalsha" of "Redis" has incompatible type "bytes"; expected "str"

Expected behavior

In an evalsha call, the 3rd argument and beyond should allow any encodable type without causing typing errors in mypy.

Logs/tracebacks

Argument 3 to "evalsha" of "Redis" has incompatible type "bytes"; expected "str"
