Problem with deploying branches on Vercel since today

[dan-the-dev]

Hi all,
we use this action from some months and it works pretty good.
Sadly, today we are facing an issue that seems related to it: the host name that is calculated and given to Vercel is different: it seems like it's using the admin username instead of branch name. Here's is an example of the right host name, correctly calculated by this action since yesterday, and the wrong one that is calculated today:

The right one: https://project-name-**git-master**-mymenu.vercel.app/
The wrong one: https://project-name-**lollo64**-mymenu.vercel.app/

(we use master as automated deployed branch to staging environement, lollo64 is the username of the admin)

We checked if there was some kind of updated and seems there is not, but we can see some github actions deployments run yesterday, triggered by Dependabot. Maybe this can be related to the problem?
