Connect options should warn us about chainIds formated as strings

[sembrestels]

Right now Connect only accepts:

<Connect
    location={orgAddress}
    connector="thegraph"
    options={{network: "xdai"}}
>

and:

<Connect
    location={orgAddress}
    connector="thegraph"
    options={{network: 100}}
>

but it doesn't work when:

<Connect
    location={orgAddress}
    connector="thegraph"
    options={{network: "100"}}
>

It should warn when a number is passed as a string, because otherwise it is not clear for the dev why the DAO is not loading.
