Typo in stepWeights documentation

[robcortez]

Describe the bug

There is an issue in the "usage" documentation regarding stepWeights. The example provided contains a typo that leads to a great deal of confusion.

Excerpt from docs:

# canary.yaml
spec:
  analysis:
    stepWeights: [1, 2, 10, 80]

This configuration performs analysis starting from 1, going through stepWeights values till 80.
We would have steps (canary weight : primary weight):

• 1 (1 : 99)

• 2 (2 : 98)

• 10 (10 : 90)

• 80 (20 : 60)

• promotion

To Reproduce

NA

Expected behavior

The final step in the example should be represented as:

• 80 (80 : 20)
