FuelLabs/fuels-rs#1477

Description

Refactored code to handle Unknown transaction types, ConsensusParameters and Blocks.

For transactions I have craeted a new TransactionType that we can try_into the fuel_tx::Transaction.
For ConsesnsuParameters and Block I have used cynic's fallback attrbute and added a Unknown variant for all Version enums.

I had to bump cynic to 3.1.0 and reqwest to 0.12.0 to use the fallback attribute on enums.

Note: I have not added tests for the changes in the endpoints. I was not sure how that should be done.

BREAKING CHANGES:
graphql endpoints for transactions use the new TransactionType type instead of fuel_tx::Transaction
