License notice?

[eitsupi]

Not limited to this repository, but if we install the quarto extension, our repository will include the filter scripts, etc., so it would be easier to handle if the License is written in each file, or _extension.yml.

License could also be within the _extensions/NAME directory.
This way, the license is propagated when quarto install extension (or quarto use extension for templates) is used.

[cscheid]

The main issue here is that we want to keep all quarto extensions in quarto-ext consistent, so whatever we change, we'll have to change everywhere else.

[mcanouil]

License guidelines should be provided in the documentation as well once the strategy is established.
This will "ensure" some consistency across all templates/extensions, even the ones not in @quarto-ext.
