Fix new errors in WolfTPM PDF generation due to long lines

[padelsbach]

Docker workflow recently started failing while generating the WolfTPM docs with the following error:

#17 2.432 [info] Rendering api/md//docs_2README_8md.md
#17 2.433 [info] Rendering api/md//index.md
#17 2.433 [info] Rendering api/md//index.md
#17 24.76 Error producing PDF.
#17 24.76 ! Dimension too large.

Example run here. And here.

Suspect this is due to an update of the texlive/texlive:latest Docker container.

This change adds a Perl regex to reformat long Markdown tables into code blocks to avoid the error.
