Every line is transformed as header element in markdown

[saravmajestic]

Describe the bug
Thanks for this library. Very much helpful. I am seeing a weird issue. When parsing this PDF, each and every line is transformed as a header element instead of sentences/paragraphs. This issue is happening with original repo as well. Tested here: https://pdf2md.morethan.io/

To Reproduce
Steps to reproduce the behavior:

1. call @opendocsg/pdf2md in cmd line with the above file as input
2. Check the output

Expected behavior
Some of the text in the pdf, for ex: Selecting the “right” amount of information to include in a summary is a difficult task. A good... should not be treated as header

Screenshots
If applicable, add screenshots to help explain your problem.
