This Pull Request introduces the corepack dependency, necessary for the
Testdriver infrastructure to run.
## Rationale:
Corepack enables faster installations and is required for `yarn`
By default, corepack is not installed on the testdriver infrastructure,
necessitating this addition.
## Benefits:
Allows better handling of `yarn` installation.
## Testing:
Local testing has confirmed successful corepack installation and
functionality within the testdriver infrastructure.
