Preserve line breaks when removing HTML comments.

For No-Issue: <!--\nhint\n-->## Tests, replace joins the first and last lines. noIssueReason then returns ## Tests, although the No-Issue: line has no reason. A PR template with this shape can pass the required check without an explanation. Preserve comment line breaks before applying NO_ISSUE. (raw.githubusercontent.com)

[ERROR] 23-23: A nonliteral argument is passed to exec/execSync. Identify the receiver: Node child_process methods execute shell commands, while regular-expression and database methods have different contracts. For shell execution, prefer execFile or spawn with an argument array.

Review comment at @.github/scripts/linked-issue.js at line 23:
Update the comment-removal step before NO_ISSUE.exec so removing HTML comments
preserves their line breaks; ensure noIssueReason does not treat following text
as a reason when the No-Issue line is empty.

Pull requests from GitHub App bots, such as Dependabot, pass.

If the check fails, add the key to the title or the body. Then push a commit or run the check again. GitHub does not run the check again when you only edit the title or the body.
If a pull request has no issue, add a line to the body that starts with `No-Issue:` and gives the reason, for example `No-Issue: fix a typo in the README`. The check passes and shows the reason as a notice. A `No-Issue:` line with no reason does not count.

If the check fails, add the key to the title or the body, or add a `No-Issue:` line to the body. Then push a commit or run the check again. GitHub does not run the check again when you only edit the title or the body.
