The contents of the tests/format/markdown/spec folder date back to #2943 (June 2017). CommonMark spec has been updated since then and enumerates 652 examples (v0.30) instead of 616 (v0.25).

We should probably sync the list of examples to make sure that nothing is missing. Getting the sequencing right should improve DX too. In the meantime, I have inserted a few files named commonmark-0.30-example-xxx.md to close the gap.

@ikatyang do you remember using any automation to populate the examples?
