Cannot access sub dependencies from @substrate/dev:@0.7.1

[bee344]

Txwrapper cannot access the subdependencies from @substrate/dev, which forces us to add them manually to devDependencies. This carries the problem that we now have two repos with deps that need to be kept up to date, which is cumbersome. Once the problem is rooted out ¿, we need to remove them from devDependencies:

    "rimraf": "3.0.2",
    "ts-jest": "^29.1.1",
    "typedoc-plugin-markdown": "^3.11.8",
    "typedoc-plugin-missing-exports": "^0.22.6",
    ```

This is getting fixed by paritytech/substrate-js-dev#129 . Once a new version is released, we can close this,
