fix(reporters): keep new-query bullets on separate lines

[veksen]

Problem

When the PR comment lists more than one entry under This PR introduces new queries, the bullets render glued onto one line instead of as a list:

… cost 1 · no index suggestion**- SELECT** "id", … FROM "item_watches" LIMIT 50;

Seen on https://github.com/veksen/d2armory-next/pull/836.

Root cause

github.ts configures nunjucks with trimBlocks: true, which strips the newline immediately after any %} block tag. The new-queries loop in success.md.j2 ended each line on {% endif %}, so the newline separating iterations was consumed and consecutive - bullets ran together — Markdown then can't parse them as a list.

Every other loop avoids this: most end on literal text, and the improves queries loop deliberately ends with {{""}} (an output tag, not a block tag) so the newline survives. The new-queries loop was the only one missing that guard.

Fix

Append {{""}} to the end of the new-queries line, matching the improves-queries loop.

Test

Added a github.test.ts case rendering two displayNewQueries and asserting the bullets stay on separate lines. Verified it fails on main (reproduces no index suggestion- <code>SELECT …) and passes with the fix.

Closes #158
