Create list of countdowns for other dates

[willgarrett64]

At this point, a single functional countdown (for Christmas) should be functional. Build out an object (or JSON file) with multiple dates to countdown to. This could include:

• Religious holidays (Christmas/Easter/Eid/Diwali/Etc)
• New Year
• Launch to something famous (such as next season of ....)

The list itself isn't hugely important for now, but just make sure there are a few to use.

You will then import these countdowns into the Select Countdown sidebar (removing the hardcoded list).

Currently the object being passed into the clock function looks like this:

{
  name: "Christmas",
  date: "2021-12-25", 
   time: "00:00"
}
