clicking tag in blog detail leads to 404 error

[koebel]

currently, clicking on a tag in the detail view of a blog post opens the following url with 404 error page: https://blog.jankaritech.com/tag

As a reader, I would expect that clicking on a tag would show me a list with other blog posts with the same tag as suggested in #140.
If this functionality is not intended, then a better user experience would be provided by removing the link from the tag.
