Investigate why the order for parsing for blurb is inconsistent

[JoanneHing]

Please include the steps to reproduce the bug.

When running test cases for the author and chart blurb, you can find out that when multiple blurb is in the markdown, the order of the blurb is parsed is not as how it is expected.

What was expected to happen?

We will expect the blurb to be parse following the order in the summary.json (blurb 1 -> blurb 2 -> blurb 3)
But now repo blurb are parsing in order of (2 -> 1 -> 3) and chart in (3 -> 2 -> 1) which is unexpected. This does not actually affecting the project as the order of the blurb is parsed is not important, but it would be nice if the reason that affect the parsing order.

What actually happened? Please include a screenshot of the output.

May refer to the summary.json files in the system test and look for the field of author blurb and chart blurb to see the orders.
