Single newlines in tags get rendered as-is in Discord

[n0Oo0Oo0b]

According to the markdown spec, lines separated by a single newline should be joined with a space.

Discord embeds doesn't seem to respect this, as demonstrated by the !traceback tag:

bot/bot/resources/tags/traceback.md

Lines 5 to 8 in 13927ec

	Please provide the full traceback for your exception in order to help us identify your issue.
	While the last line of the error message tells us what kind of error you got,
	the full traceback will tell us which line, and other critical information to solve your problem.
	Please avoid screenshots so we can copy and paste parts of the message.

We could resolve this by formatting paragraphs on a single line, but I think joining the lines manually as the tag is loaded is better (something along the lines of re.sub(r"(?<!\n)\n(?!\n)", " ", content)) since it leaves open more formatting options.
