Make it possible to override mint & burn methods in L2StandardERC20

feat: set owner task

Creates a task that can set the owner of any contract that is `Ownable`.
It defaults to attempting to set the address of the `OVM_GasPriceOracle`
on L2. The following config options must be set:

- `CONTRACTS_RPC_URL`
- `CONTRACTS_DEPLOYER_KEY`

It can be invoked like so:

```
$ npx hardhat set-owner --owner 0x..
```

On L2 networks that do not enforce transaction fees, the
`--transaction-gas-price 0` config option may be used for
convenience.

This script also supports Ledger with the `--use-ledger` flag.
It defaults to deriving a key at the `ethers.utils.defaultPath`.

l2geth: prevent too low of fees from getting through

There was a bug in the floating point math that allowed
for transactions with extremely low fees to get through.
This PR fixes that bug as well as adds additional test
cases.

l2geth: fix bad flag parsing

The parsing of the `ROLLUP_FEE_THRESHOLD_UP` and
`ROLLUP_FEE_THRESHOLD_DOWN` config options were set to be boolean flags
instead of float64 flags. The config flags wouldn't parse if a float64
was used as a bool flag.

l2geth: only accept txs with exact nonce

Dynamically generate predeploy contracts markdown

This PR makes it so that the sequencer will
only accept transactions if the nonce exactly
matches what is in the state. This is because the
mempool in upstream geth has different rules than
what l2geth needs.

This prevents issues with local nonce managers that
send transactions with a too large of nonce and
end up having all of the transactions revert since
the transaction is still accepted but reverts
in the OVM

The sequencer will reject transactions when the fee
is too large to prevent users from accidentally sending
transactions with a huge fee.

This PR adds an actionable error message for when
the fee is too large.

gas-oracle: improve logging

contracts: lint the tasks directory

ci: handle gas-oracle latest image, skip builder

This PR lints the tasks directory

This PR updates the `ops/scripts/ci-versions.js` file
to skip building the builder image for when there
are changes to the `gas-oracle`. The `builder` contains
all of the JS code required for the various typescript
based services.

This PR also publishes `ethereumoptimism/gas-oracle:latest`.
It is faster to `docker pull` than `docker build`.
This will speed up the workflow for developers building locally
against the `docker compose` setup as well as the CI if it
is refactored to pull the `latest` images for the unchanged images
instead of building them from scratch.

l2geth: allow 0 gasprice txs for `OVM_GasPriceOracle.owner`

This PR allows the owner of the `OVM_GasPriceOracle` to send
transactions with 0 gas price when the enforce fees config option
is turned on.

The L2 gas price is currently updated by sending transactions to the
chain to a special contract. In the future it should be updated as a
side effect of transaction execution. Having the gas price on chain is
important so that it can be replicated accross the network to ensure
that users can send transactions with a high enough fee.

Having the `OVM_GasPriceOracle.owner` key not need to maintain
ETH on L2 is an operational simplification as well prevents a
terrible scenario where a bug causes the L2 gas price to go so high
that it is impossible for the owner to update it.
