Fix escaping in *** Punctuation.

[Klafyvel]

I don't know if that's on purpose, but just in case it is not, I fixed escaping within the inline code block that describes punctuation.

Actually, this is intentional. Free-form verbatim attached modifiers have a higher precedence than the escape sequence:

norg-specs/1.0-specification.norg

Lines 1703 to 1704 in efcb578

	~ Verbatim {# free-form attached modifiers} (`\|``|`, `\|``|`)
	~ {# Escaping}[The escape character] (`\`)

You may still see this as being escaped though, as long as nvim-neorg/neorg#621 is not yet merged.

Ok ! thanks for the explanation. :)
