contracts-bedrock: delete dead delete output code

We have migrated to using `superchain-ops` for any sort
of safe interactions. This code will likely need to be ported
over to the `superchain-ops` repo in the future. It is not
necessary for now, so delete it.

-## L2 Output Oracle Scripts
-
-A collection of scripts to interact with the L2OutputOracle.
-
-### Output Deletion
-
-[DeleteOutput](./DeleteOutput.s.sol) contains a variety of functions that deal
-with deleting an output root from the [L2OutputOracle](../../contracts/L1/L2OutputOracle.sol).
-
-To delete an output root, the script can be run as follows, where `<L2_OUTPUT_INDEX>` is
-the index of the posted output to delete.
-
-```bash
-$ forge script scripts/output/DeleteOutput.s.sol \
-  --sig "run(uint256)" \
-  --rpc-url $ETH_RPC_URL \
-  --broadcast \
-  --private-key $PRIVATE_KEY \
-  <L2_OUTPUT_INDEX>
-```
-
-To find and confirm the output index, there are a variety of helper functions that
-can be run using the script `--sig` flag, passing the function signatures in as arguments.
-These are outlined below.
-
-### Retrieving an L2 Block Number
-
-The output's associated L2 block number can be retrieved using the following command, where
-`<L2_OUTPUT_INDEX>` is the index of the output in the [L2OutputOracle](../../contracts/L1/L2OutputOracle.sol).
-
-```bash
-$ forge script scripts/output/DeleteOutput.s.sol \
-  --sig "getL2BlockNumber(uint256)" \
-  --rpc-url $ETH_RPC_URL \
-  <L2_OUTPUT_INDEX>
-```
