Play with runners

[pgrange]

Contributes to #761

We want to run the smoke tests on mainnet but that means that we need way more resources than we used to need when only running them on preview or preprod. Just caching the cardano database between two runs will not work anymore or take forever as it's way bigger.

To solve that, we invest in a self-hosted GitHub runner dedicated to running the smoke tests and that will persistently keep the cardano-node database on disk between several runs.

This P.R. updates the C.I. so that the smoke tests use the runner. It also describes the procedure to install a GitHub runner for this. A runner has already been setup and smoke test do work on it:

• smoke test on preview
• smoke test on preprod
• smoke test on mainnet (fails because no cash here but that's ok)

Transactions Costs

Sizes and execution budgets for Hydra protocol transactions. Note that unlisted parameters are currently using arbitrary values and results are not fully deterministic and comparable to previous runs.

• The minting policy hash is only usable for comparison. As the script is parameterized, the actual script is unique per Head.

Didn't we also install nix by hand here or was this done by the workflow?
