`fetchVersion` only works if the extension was built

Description

This is rather a request for confirmation than a bug report.

In _version.py, fetchVersion searches package.json in the current folder (that is the folder of the python sources):

https://github.com/jupyterlab/extension-cookiecutter-ts/blob/3.0/%7B%7Bcookiecutter.python_name%7D%7D/%7B%7Bcookiecutter.python_name%7D%7D/_version.py#L7

This means the version resolution works only if the extension was built (i.e. there is a labextension folder containing the package.json in the current folder).

Is this the desired behaviour ? Would it not be more robust to search directly for package.json in the extension folder (i.e. the parent folder of the python sources) ?

Yes indeed.

Unfortunately, we can not look outside of the python package as that code may not be in the source folder.

Ah indeed, I understand now. Thanks for the clarification !
