feature: allow to hide tag history to simplify the user interface

I would like to use docker-registry-ui to inform users about the available
tags for our images. The users of this interface are not interested in the
technical backgrounds how it works and I worry that it would confuse them.

Note: One needs to be aware, that this is data is available nonetheless. This
is only a user interface switch for hiding the button.

 - `CATALOG_MAX_BRANCHES`: Set the maximum repository/namespace to expand (e.g. `joxit/docker-registry-ui` `joxit/` is the repository/namespace). Can be 0 to disable branching. (see [#319](https://github.com/Joxit/docker-registry-ui/pull/319)). (default: `1`). Since 2.5.0
 - `TAGLIST_PAGE_SIZE`: Set the number of tags to display in one page. (default: `100`). Since 2.5.0
 - `REGISTRY_SECURED`: By default, the UI will check on every requests if your registry is secured or not (you will see `401` responses in your console). Set to `true` if your registry uses Basic Authentication and divide by two the number of call to your registry. (default `false`). Since 2.5.0
+- `HIDE_TAG_HISTORY`: Allows to disable the tag history feature to simplify the user interface. (default `false`).
 
 There are some examples with [docker-compose](https://docs.docker.com/compose/) and docker-registry-ui as proxy [here](https://github.com/Joxit/docker-registry-ui/tree/main/examples/ui-as-proxy/) or docker-registry-ui as standalone [here](https://github.com/Joxit/docker-registry-ui/tree/main/examples/ui-as-standalone/).
