Description

As initiated in https://github.com/squidfunk/mkdocs-material/discussions/4393 I propose allowing users to display post tags on the index pages.

Quite often tags are visible on the index pages, especially when tags are the only taxonomy used in a blog (no categories). Hence I propose to make them subtly visible somewhere in the post meta.

To support my point, here are some blog themes that display tags in their posts:

Use Cases

Allowing users to navigate to the relevant topics by following the tags visible on the index page

Screenshots / Mockups

A coarse example shows tags being displayed after the post date info. I didn't add tag's visual styling, but this is mere because I don't know how to do this quickly.
