Pipeline Overview > Processing Timeline out of order

## Expected Behavior
On the Pipeline Overview, I expect that the "Processing Timeline" will show the timeline in numerical order (as it does on the Pipeline detail page).

## Current Behavior
The "Processing Timeline" appears to be sorted left to right in alphabetical order, causing stages with more than one digit to be out of order.


## Possible Solution
Sort the processing timeline numerically rather than alphabetically.

## Steps to Reproduce (for bugs)
1. Add the following Pipeline stages to a pipeline: Stage 1, Stage 2, Stage 100
2. Observe that the "Processing Timeline" displays the stages in the order Stage 1, Stage 100, Stage 2

## Context
There is no functional deficiency as far as I can tell. It's simply confusing and alarming to see the Processing Timeline in the incorrect order.
