Add end-to-end benchmark results to documentation

[ghost]

Adds a page containing result(s) of running end-to-end benchmarks in the CI. At the moment, it contains a single benchmark with a very simple content displayed:

Future works might include:

• Add more pages/sections for different scenarios
• Include graphs displaying the execution profile of each benchmark

Fix #186

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.

Only the avoidable unsafePerformIO makes me not approve this right away. Also had some other suggestions.

Result looks great

When the benchmark fails we get some info on the source location:
