When we run `make docs-clean`, it deletes the venv, which isn't great. However, simply updating `VENVDIR` to `DOCS_VENVDIR` takes us back to an old issue, where `rm` doesn't delete anything: ``` DOCS_VENVDIR= make -C docs clean --no-print-directory git clean -fx "_build" rm -rf _dev/.doctrees rm -rf rm -rf _dev/node_modules/ rm -rf _dev/styles rm -rf _dev/vale.ini ``` The `docs-clean` target in the docs Makefile has an ambiguous `test` command that fails if we export a temp directory to it. To work around that, this PR overrides the target completely, so we don't require a temp dir to delete in the first place. --- - [x] I've followed the [contribution guidelines](https://github.com/canonical/starbase/blob/main/CONTRIBUTING.md). - [x] I've signed the [CLA](http://www.ubuntu.com/legal/contributors/). - [x] I've successfully run `make lint && make test`. - [ ] I've added or updated any relevant documentation. - [ ] In documents I changed, I [added a meta description](https://canonical-starflow.readthedocs-hosted.com/how-to/add-a-page-meta-description/) if one was missing. - [ ] I've updated the relevant release notes.
