Minor documentation issues

[schuemie]

For a next release, it might be good to fix these:

1. The documentation website still lists version 0.0.1.994 as the current version. Next time make sure to generate the website as one of the last steps (after updating the version number).
2. The documentation website is missing the GitHub link in the top right corner (see the CohortMethod site as example. I must admit I'm not sure why that is. The _pkgdown.yml looks fine.
3. The vignette titles are bit ugly, like 'Capr_Attributes_Extended', instead of perhaps 'Using extended cohort attributes in Capr', which would be both human-readable and more informative.
4. The Documentation section in the README doesn't list all vignettes.
5. The Installation section in the README mentions a checkCmInstallation() function that is not part of Capr.

Additionally:
6. The Github Action badge in the README currently links to https://github.com/OHDSI/<reponame>/actions?query=workflow%3AR-CMD-check, which is not a valid URL. I recommend replacing <reponame> with Capr.

Not sure why the github link is not working either. I used the template code of the other packages. I will keep looking at the files and see if I find something.

Other issues have been addressed and the package down site has been updated (forgot to update before the release).

This issue will close once I accept the pull request linked to these issues

I found the issue with the missing GitHub link: the link to the GitHub site must be in the DESCRIPTION file. I took the liberty of pushing this fix to the develop branch.

Next time please remember to call fixHadesLogo after regenerating the website.
