FEATURE REQUEST: Tags column (formatter) for dynamic block

This would be very simple and is an obviously missing feature.

It should be possible to filter the tags with regexp.

I fixed it for me with the following el-patch for (org-dblock-write:org-ql):
```
(el-patch-add
(cons 'tags (lambda (element &optional pattern)
(s-join " "
(--filter
(or (not pattern)
(s-matches? pattern it))
(org-element-property :tags element))))))
```

As stated in my other feature request, tags and property columns should be able to access inherited tags/properties. This information is currently not accessible via the element parameter of (org-dblock-write:org-ql).
