Update up-next text when auto play next episode is disabled

[ConnorS1110]

Changes
When Play next episode automatically is disabled, but the up-next popup is enabled, it still shows a countdown timer, which is misleading because it will not auto play the next episode. It now checks user configuration settings to see if you have the popup enabled and have EnableNextEpisodeAutoPlay set to false, which will now just show Next Episode/Video instead of also including the countdown timer.

I saw the new strings from this PR pop up on Weblate and noticed that the separate strings for "next episode" and "next video" have been combined into one string with a variable: Next {0} Playing in {1}, in which {0} is either Episode or Video. I believe this creates potential localisation issues.

1. In some languages, the form of the adjective (next) depends on the grammatical gender of the noun it pertains to (episode, video). For languages in which the translations for "episode" and "video" are of different grammatical genders, this creates a problem.

2. In English, Title Case is very common for dialogue texts like this, but in many languages (including Dutch, which I am most familiar with), Title Case is Never a Thing and sentence case is always used. Therefore, "episode" and "video" should not start with a capital letter in these languages, which this string change makes impossible.

I realise these points, particularly the second, might come across as nitpicky, but I did want to point them out regardless. In summary, I would suggest reverting the string changes, since as far as I understand, the previous situation worked just fine.
