Ensure references to the repository url are consistent across all templates

[ericof]

I'm trying to make sure every reference to the repository url is consistent when we create a project.

• README.md
• backend/README.md
• backend/pyproject.toml
• frontend/README.md
• frontend/packages/<>/package.json
• frontend/packages/<>/towncrier.toml

I also fixed an issue with the backend towncrier template

Fixes #221

I have not tested it, but the direction makes sense.

Tested project generation, docs with make test, project with make install, started up servers, able to browse both Classic UI and Volto, all good. Tried make test, and only tests for backend were found and all passed. Are there zero tests for Volto?

Yes, for now a new Volto add-on comes with zero tests.

I'm concerned that the instructions to install the add-on for both Volto 17 and 18 do not align with official documentation. See:

• https://6.docs.plone.org/volto/development/add-ons/install-an-add-on-dev-17.html

@sneridagh and I recently revised that document. Let's make sure he does a thorough review of this. I'm OK with keeping the customized instructions where the project name gets substituted, but let's make sure they are correct and aligned with official docs.

[stevepiercy]

This doesn't make sense. We have instructions for both Volto 17 and 18, but then say development of the add-on can be done only in Volto 18. I'm not sure what to do here.

Do we actually support Volto 17 with this Cookieplone template?

[ericof]

Add-ons developed with Cookieplone could work with Volto 17

[stevepiercy]

Then we should remove this section, right? We can't say both it works only for 18, then it also could work for 17. Maybe we just refer to the official docs?

Develop Volto add-ons

@sneridagh @davisagli what do you think?

[ericof]

Let's open a other issue to review all the README files?
The original goal of this PR was to make sure all references to the repository url were consistent within a project, but now we are trying to address all the other issues we have in docs :-)
