Bump nanoid and mocha in /src/moonbeam/contracts (#122)

Removes [nanoid](https://github.com/ai/nanoid). It's no longer used
after updating ancestor dependency
[mocha](https://github.com/mochajs/mocha). These dependencies need to be
updated together.

Removes `nanoid`

Updates `mocha` from 10.2.0 to 10.8.2
