Links in setup seem to point to old site

In SETUP.md:

```
## Download repo (if delivered another way, skip to next step, "Install Quarto CLI"

# with GitHub username and password

git clone https://github.com/cBio-MSKCC/toxicology.git

OR
# with ssh key
git clone git@github.com:cBio-MSKCC/toxicology.git
```

Should this not be: `https://github.com/mskcc/toxicology.git`?
