This email is basically phased out and replaced by [email protected], yet it requires registration.
Any suggestion for an alternative?

I don't this we should have "team" here at all. The very people who are part of it are in the list below.

I don't think we need an email either, but I do like the "Team" there. This is the citation for R, for example:

@Manual{,
    title = {R: A Language and Environment for Statistical Computing},
    author = {{R Core Team}},
    organization = {R Foundation for Statistical Computing},
    address = {Vienna, Austria},
    year = {2023},
    url = {https://www.R-project.org/},
  }

Can we use a URL instead of an email?

[baharmon]

There is an author entity website field that could be used for the url:

authors:
  - name: "GRASS Development Team"
    website: "https://grass.osgeo.org/"

@veroandreo This is different. We have team as the first one of many. R has it as the only one AFAIU.

I would prefer to remove the "team" author in a follow up PR, so I don't really care much about updating or not updating the email. To make this PR complete, the email change makes sense.
