Verify we have the right license about competition-simulator

[RealOrangeOne]

We're not distributing webots itself, nor are we making modifications to webots itself, so their license won't affect us.

In theory we're just shipping assets to be used in webots, so the license can be whatever we choose (in much the same way as shipping a Python application doesn't bind us to the CPython license).

I think MIT is fine for what we're doing, so long as there's nothing else in the repo we didn't create.

If it's the Apache licence we just need to attribute it and state any changes that we have made to the webots source.

In that case I feel like this issue is resolved
