WIP: fix: 🐛 tsconfig-paths support

Addresses #1033

Tried this locally by running tsconfig-paths/register inside of node_modules/@hapi/lab/bin/lab in my own project, and it seemed to work. In a testing environment however, the cwd gets picked up as the project root, and not that particular test, even if I pass cwd to the RunCli option:

• Verified by uncommenting this: https://github.com/hapijs/lab/pull/1040/files#diff-ec4603860f623112bc6c330ac24abc98262e5905358e19c03612b81cebfcd756R7

Any ideas would be helpful!

Closed in favor of #1041 which actually works.
