added cron job to comment ongoing referenda on PRs

[Bullrich]

Added functionality for a cron job to iterate over all ongoing referendas and compare them to the open PRs. If there is any match on the remark, and the referenda has been opened after the last time the action was run, it will comment a link to the referenda in Polkassembly.

This is intended to resolve the requirements in polkadot-fellows/RFCs#57

@Bullrich is it only for new referendas?
can it track the existing referendas status changes as it's requested in paritytech/eng-automation#2

Not yet, this first version will only obtain the status of ongoing referendas. After this I can make a second PR handling completed referendas

Would love to see it working for a several days on stg before implementation
How you think the further referenda status changes will be tracked?

[Bullrich]

Hi @rzadp! It is ready for review.

I don't really know what tests I can add aside from ensuring that it doesn't crash when fetching the referenda. If you have any suggestions, please, let me know.

Me too. Do you know how to setup an alternative testing environment so I can start testing it?

You mean when they close? It should be doable using @rzadp's method, so the logic wouldn't change too much.

answered in our matrix channel - could be Westend -> Collectives with making us fellows there installed to paritytech-stg?
