[deps] Replace faker with @faker-js (#201105)

## Summary

The `faker` library is[ not maintained
anymore](https://fakerjs.dev/about/announcements/2022-01-14.html#i-heard-something-happened-what-s-the-tldr)
and is replaced by a community fork `@faker-js`.
This PR migrates all the usages of faker to the new library, trying to
use the same methods (even if they have slight differences in results
like `faker.random.number()` has a max of 99999 where instead
`faker.number.int()` have a MAX_SAFE_INTEGER as max).
