add MD5 slot on Rococo

[tlacloc]

Description:

A MD5 Slot is a critical feature that needs to be added to Rococo, which is the testnet for Parachains. This slot will enable the secure storage and retrieval of data on the Parachain. Additionally, we need to connect Rococo to the Relay Chain, which will enable interoperability with other Parachains and the Polkadot ecosystem. To achieve this, we will follow the steps outlined in the tutorial: "Connect to a Relay Chain" (https://docs.substrate.io/reference/how-to-guides/parachains/connect-to-a-relay-chain/).

The main reason for this change is to enhance the functionality of Rococo and enable interoperability with the Polkadot ecosystem.

Tasks:

• Add the MD5 Slot to Rococo by following the instructions in the tutorial.
• Modify the runtime configuration to enable the MD5 Slot.
• Build and deploy the modified Rococo parachain.
• Connect Rococo to the Relay Chain by following the instructions in the tutorial.
• Test the implementation thoroughly to ensure accuracy and consistency.

Expected Outcome:

Once implemented, Rococo will have a MD5 Slot, which will enable secure storage and retrieval of data on the Parachain. Additionally, Rococo will be connected to the Relay Chain, which will enable interoperability with other Parachains and the Polkadot ecosystem. This change will enhance the functionality of Rococo and ensure that it is compatible with the wider Polkadot network.
