[Bug] Repo url of open data handbook is compromised

## Description
Due to some previous commits, the repository button of open data handbook resource is not displayed. I think that the commit responsible for this bug is [this](https://github.com/creativecommons/cc-resource-archive/commit/797ed1c18d0bfcd34c4430f6177ccc3502a1ac6a).

The repository url that was compromised : [Link](https://github.com/okfn/opendatahandbook)

## Reproduction

1. Go to https://resources.creativecommons.org/open-data-handbook/
2. See the download button.

## Expectation
This bug can be fixed by adding the Repository button back.
If this was intentional, the `repourl` from `opendatahandbook.html` can be removed to resolve this bug.
