jsii-pacmak: H5 tags on Markdown files break Python packaging

[automartin5000]

Describe the bug

.md files that have H5 tags (#####) and are included to be packaged is breaking packaging with:
TypeError: Cannot read properties of undefined (reading 'repeat')

Expected Behavior

jsii-pacmak completes Python packaging successfully

Current Behavior

TypeError: Cannot read properties of undefined (reading 'repeat')

Reproduction Steps

I have inline documentation to be generated by jsii-docgen. I have no issues when I use H1-H4 header tags in my JsDoc-style comments. But when I use H5 header tags (#####), jsii-pacmak fails on Python packaging. This completes successfully for Javascript. Compilation succeeds successfully.
