Fix missing backtick and incorrect variable in DiagnosticLinkInlineParser

[Copilot]

Two string manipulation bugs in DiagnosticLinkInlineParser.cs:

Changes

• Line 275: Added missing closing backtick in error message

  - processor.EmitError(link, $"`{url}` does not exist. If it was recently removed add a redirect. resolved to `{pathOnDisk}");
  + processor.EmitError(link, $"`{url}` does not exist. If it was recently removed add a redirect. resolved to `{pathOnDisk}`");

• Line 343: Fixed incorrect variable reference in LastIndexOf call

  - : newUrl.Remove(url.LastIndexOf(".md", StringComparison.Ordinal), ".md".Length);
  + : newUrl.Remove(newUrl.LastIndexOf(".md", StringComparison.Ordinal), ".md".Length);

  Using url instead of newUrl caused incorrect index calculation when removing .md extensions from modified URLs.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• d31bhlox0wglh.cloudfront.net
  • Triggering command: /home/REDACTED/work/docs-builder/docs-builder/.artifacts/bin/Elastic.ApiExplorer.Tests/release/Elastic.ApiExplorer.Tests /home/REDACTED/work/docs-builder/docs-builder/.artifacts/bin/Elastic.ApiExplorer.Tests/release/Elastic.ApiExplorer.Tests @@ /tmp/tmp041fVD.tmp (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
