epoch converted to number in 'near validators <epoch>'

closing #666

[bowenwang1996]

I am not sure what this is supposed to do. Epoch id is not an integer and cannot be parsed as such

[volovyks]

@bowenwang1996 looks like the function parameter should be called blockNumber (Docs: https://docs.near.org/docs/api/rpc#detailed-validator-status). And it should be a number, not a string. Thanks for pointing this out!
P.S. Check the attached issue for more context.

@volovyk-s looks like there is opportunity to pass block hash as well – we should support passing either IMO.

Note that in case you want to have yargs always parse some option into number there is such possibility:

(won't work for the case when you need to support both block hash and number though)

Updated.
To avoid breaking changes I have not added new options (--blockHash and --blockNumber).
