I have recently updated to Quarto 1.3 but it seems is creating problems when I am trying to deploy my blog. 

I am using Github pages and for deployment, I am just using the publish command in the terminal. 

I have found out that after I start using Quarto 1.3 the process for deployment [seems to be erasing the CNAME](https://github.com/msh855/TheQuantEconomist/commit/146e92b9f99ec3d80b45be67884e4d4511586830#diff-76b26edb75578663ca0fd6515ec7880ca04046bdbab298938981c9f0bd3907dd) file needed for the custom domain: 

This is causing Github to also revert back to the default url, and not my custom domain.
