Create a provider using ethers.getDefaultProvider()

[Elemino]

Attempted to create the ethers.js provider but not sure if this should be declared globally and if so, where it should be declared.

Once the provider is successfully instantiated, the next step should be to migrate all the read-only method calls for listing cards, adding wallet signers etc.

I have a lot of gumption to keep working on this great project but might need a bit more guidance.

Let's make a separate ethersService like https://github.com/VolcaTech/cryptoxmas.xyz/blob/master/src/services/web3Service.js
with the similar setup method and getProvider instead of getWeb3

Had the wrong conceptions of a few basic things but I'm getting there via trial and error. I expect to complete the PR in two days. Thanks.
