op-e2e: Fix bug in TestWithdrawals

Co-authored-by: Andreas Bigger <abigger87@gmail.com>

The existing TestWithdrawals test attempts to assert that the total fees
of the prove and finalize transactions are accounted for in the L1
balance.  But, it re-uses the `calcGasFees` function and passes in the
`GasTipCap` and the `GasFeeCap` from the L2 transaction, not from the
actual L1 transactions.  In the event that the gas fee differs on the L2
from the L1, then the test will fail.

To keep the diff small, this change simply multiplies the GasUsed and
`EffectiveGasPrice` from the receipts.  This could be moved into a
helper function like `calcGasFees`.  Using the `EffectiveGasPrice` seems
just as good or better than relying on the parameters of the original
transaction, and could be similarly utilized higher in the test for the
L2 fees.  If we really want to get the parameters from the tx, then
`ProveAndFinalizeWithdrawal` would need to be modified to return the
txes.

fix(op-bootnode): Add go-reviewers as codeowner

Removes the `l2geth-exporter` package from the monorepo.
This exposed metrics for the legacy system and is no longer
necessary.

infra: delete

This commit deletes the `infra` directory, which contained a package
called `op-replica`. This package contains docker + k8s tooling to
bring up a legacy system. It is not used and therefore can be deleted.

integration-tests: deprecate
