Enforce setuptools<70.0.0

[gdewael]

Hi,

Following the instructions to install in the README.md to evaluate the pre-trained checkpoint raises an error:

looking for. ./SpecBridge_MassSpecGym_dataset.mgf and None
Error using dreams encoder from checkpoint ./ssl_model.ckpt: No module named 'pkg_resources'
Error using dreams encoder from checkpoint ./ssl_model.ckpt using DreamsEncoder: cannot import name 'DreamsEncoder' from 'dreams' (./SpecBridge/DreaMS/dreams/__init__.py)
Using dummy dreams encoder

This issue arises due to recent versions of setuptools losing pkg_resources as a dependency, breaking DreaMS.
Specifying - setuptools>=61.0,<70.0.0 in environment.yml fixes the issue.

I could succesfully reproduce your work after this step. Nice work!
