FEATURE: _data/packages.yml should be alphabetically ordered

[pllim]

Is your feature request related to a problem? Please describe.

Astropy cross-lists https://www.pyopensci.org/communities/astropy.html packages over at https://www.astropy.org/affiliated/index.html#affiliated-package-list . We do so by parsing https://raw.githubusercontent.com/pyOpenSci/pyopensci.github.io/main/_data/packages.yml "in real time" directly (insertion ordered).

Describe the solution you'd like

The packages to be listed alphabetically like https://www.astropy.org/affiliated/index.html#affiliated-package-list-pre-ape22 . It is easier to find a package when the list get long eventually.

Describe alternatives you've considered

We could try to sort it ourselves but that would take extra processing on our end, and also then our listing order would diverge from your listing order.

Additional context

Thought of this while working on astropy/astropy.github.com#651

[pllim]

After some "offline" discussions, it appears that astropy and pyos can probably do sorting on the front end themselves without changing the YAML file.

Thanks @pllim.
