Write a function find_plateaus that receives a list of integers as parameters. Your function should find and return a list of plateaus, which are numbers that are equal to both of its neighbors.

Question
Write a function find_plateaus that receives a list of integers as parameters.
Your function should find and return a list of plateaus, which are numbers that are equal to both of its neighbors.
IMPORTANT NOTES:
- the first and last values can not be plateaus;
- the plateaus should be in the order they appear in the original list;
- the same value might be a plateau in multiple places in the original list;
- there might be no plateaus, in which case you should simply return an empty list.
Example 1:
If the function call is:
find_plateaus([1, 2, 2, 2, 1])
You should return [2], because:
- 2 == 2 and 2 == 2.
Example 2:
If the function call is:
find_plateaus([10, 2, 20, 4, 4, 4, 5, 8, 5, 5, 5, 5])
You should return [4, 5, 5], because:
- 4 == 4 and 4 == 4;
- 5 == 5 and 5 == 5;
- 5 == 5 and 5 == 5
