Revert "Fix parsing fenced code blocks: include EOL in closing marker"

This reverts commit 5c70fe6.
Including EOL characters to fenced code blocks breaks many other tests.
We have to adapt parsing PlantUML code blocks instead and let them
no longer include the EOL characters at the end of the last code block line.
