Adminhtml - Too many mage-translation-file-version cookies

[ihor-sviziev]

Preconditions (*)

1. Magento 2.3.4 or 2.4-develop
2. Enable "Add Secret Key to URLs" in Stores > Configuration > Advanced > Admin > Security (enabling this option recommended for production env, it increases issue reproducing)

Steps to reproduce (*)

1. Login into the admin
2. Go to few different pages
3. Open Chrome developer console, Network
4. Refresh the page
5. Select "document" request, see "Cookies" tab on the right side
6. check "show filtered out request cookies"
7. See list of cookies

Expected result (*)

1. Maximum one cookie mage-translation-file-version and mage-translation-storage should be created

Actual result (*)

1. Almost for all admin URLs were created separate cookie mage-translation-file-version and mage-translation-storage because each of them has own path:
   

Additional info

After some time of navigation on the admin and frontend - browser reaches limit per domain (in chrome 180 cookies per domain) and drops older cookies. In my case it started dropping 2fa auth cookie, and I have to put 2fa code all the time when I log in into the admin

That would be awesome if you find the time to add Functional Tests for that change.
You can use one of these commands:

        <grabCookie stepKey="" />
        <resetCookie stepKey="" />
        <seeCookie stepKey="" />
        <setCookie userInput="" value="" stepKey="" />
