This came up in https://github.com/quarto-ext/code-filename/issues/4

Quarto allows to install from a file (https://quarto.org/docs/extensions/distributing.html#archive-files) but expect a specific structure. When downloading from Github source, there is a parent folder to the repo folder. 

We could maybe check for that structure instead of just directly looking for the `_extensions` folder.

See discussion in the issue link
