This requires setting up a PRIVATE_KEY environment variable for the account that's going to do the deployment, let's add that to the docs

**Motivation** Verifying TDX attestations on-chain is expensive (~5M gas), so it would be better to avoid them if possible **Description** By generating a private key inside the TDX VM (where the host can't read it), attesting it's validity and then using it to sign updates it's possible to massively decrease gas usage.

**Motivation** In #2677 an example of a TDX-based prover was made. This uses the example code to add a prover. **Description** TDX is added as another prover, and made to use the same API
