fix(markdown): escape pipe characters in table cells

Pipe characters ('|') in Markdown table cells are now replaced with an
escape sequence ('\|') to ensure that cells are not split by Markdown
renderers.

Tests which expected pipe characters to be unescaped, which is
incorrect, were updatedto expect an escape sequence and new test cases
to ensure the correct escaping behavior were added.
