Grapify tags API

## What does this MR do?

Add the Grape-DSL to the tags API.

## Are there points in the code the reviewer needs to double check?

The delete endpoint only has a description but no success entity because we don't have one. We only return the branch name as JSON. Should I do something else?

## What are the relevant issue numbers?

Related to #22928

Replace jquery-cookie plugin with js-cookie

## What does this MR do?

Removes an outdated and unmaintained dependency [jquery.cookie](https://github.com/carhartl/jquery-cookie) with its successor [js.cookie](https://github.com/js-cookie/js-cookie) which is not dependent on jQuery.

Also this MR adds a global default cookie `path` setting which defaults to the GitLab root directory.  Now, setting a cookie to any path other than `gon.relative_url_root` requires an explicit opt-out.  This is a sensible default and should prevent accidental omission going forward.

## Are there points in the code the reviewer needs to double check?

Double check that all instances of `$.cookie(x)` have been replaced by `Cookies.get(x)` and all instances of `$.cookie(x, y, z)` are replaced with `Cookies.set(x, y, z)`.  All javascripts which set or retrieve cookie values should function just as before.

## Why was this MR needed?

One more step toward shaking off jQuery as a dependency (#23022), also [jquery.cookie](https://github.com/carhartl/jquery-cookie) is no longer maintained and hasn't seen an update in 2+ years.
