Previously, using ToMarkdown on a label-list would generate output that
could not be reparsed by the RDoc::Markdown parser:
```
md = <<~MD
apple
: a red fruit
banana
: a yellow fruit
MD
doc = RDoc::Markdown.parse(md)
doc # => [doc: [list: NOTE [item: ["apple"]; [para: "a red fruit"]], [item: ["banana"]; [para: "a yellow fruit"]]]]
new_md = doc.accept(RDoc::Markup::ToMarkdown.new)
new_md # => "apple\n: a red fruit\nbanana\n: a yellow fruit\n\n"
new_doc = RDoc::Markdown.parse(new_md)
new_doc # => [doc: [list: NOTE [item: ["apple"]; [para: "a red fruit\nbanana\n: a yellow fruit"]]]]
```
The issue is that the [PHP Markdown Extra spec][1] requires a newline
after each definition list item, but ToMarkdown was not putting newlines
between label-list items.
This commit fixes the issue by properly appending a newline after each
label-list item so that the output of ToMarkdown can be reparsed by
RDoc::Markdown:
```
md = <<~MD
apple
: a red fruit
banana
: a yellow fruit
MD
doc = RDoc::Markdown.parse(mdoc)
doc # => [doc: [list: NOTE [item: ["apple"]; [para: "a red fruit"]], [item: ["banana"]; [para: "a yellow fruit"]]]]
new_md = doc.accept(RDoc::Markup::ToMarkdown.new)
new_md # => "apple\n: a red fruit\n\nbanana\n: a yellow fruit\n\n"
new_doc = RDoc::Markdown.parse(new_md)
new_doc # => [doc: [list: NOTE [item: ["apple"]; [para: "a red fruit"]], [item: ["banana"]; [para: "a yellow fruit"]]]]
```

`@res` is an Array, so `@res =~ /\n\z/` calls `Object#=~` which always
returns nil.
I guess it should be `@res.last =~ /\n\z/`, but the change causes test
failures.
This bug was found during work for removal of `Object#=~`.
[Feature #15231]
