Fix operators formatting of Non Deterministic Inputs in docs

As of right now, this docs page (https://docs.miden.xyz/miden-vm/user_docs/assembly/io_operations#nondeterministic-inputs) of the VM docs displays the Non Deterministic Input operations with faulty formatting.

The correct operations would be the following:
- `adv_loadw`
- `adv_pipe`
- `adv_push.N`

Locate the documentation file for the VM's I/O operations, likely in a docs/ or user_docs/ directory. Find the section on Non Deterministic Inputs and correct the formatting of the listed operations (`adv_loadw`, `adv_pipe`, `adv_push.N`). Verify the changes by building the documentation locally or checking the rendered output.
