getMarkdownContent

Returns the Markdown content of this comment as defined in JEP 467:

Because horizontal whitespace at the beginning and end of each line of Markdown text may be significant, the content of a Markdown documentation comment is determined as follows: -- Any leading whitespace and the three initial / characters are removed from each line. -- The lines are shifted left, by removing leading whitespace characters, until the non-blank line with the least leading whitespace has no remaining leading whitespace. -- Additional leading whitespace and any trailing whitespace in each line is preserved, because it may be significant. For example, whitespace at the beginning of a line may indicate an indented code block or the continuation of a list item, and whitespace at the end of a line may indicate a hard line break.
