Write a bash script that uses an until loop to print a countdown from 5 to 1, each followed by a fun fact about that number.

Note that you can use until also to count up, it is just a different condition from the while loop. Here we just want to illustrate counting down, which could also be done with a while loop.

Example Output:

5 is the number of fingers on one hand.
4 is the number of seasons in a year.
3 is the first odd prime number.
2 is the only even prime number.
1 is the first positive integer.
