Code Review

This pull request adds a code completion snippet for Asciidoc's [WARNING] admonition block. The implementation is straightforward and follows existing patterns in the file. My review identifies one issue where the completion may not be triggered as described in the pull request. I've provided a suggestion to align the implementation with the intended behavior.

[gemini-code-assist]

The completion item label "[WARNING]" does not align with the goal of triggering this completion by typing WA, as described in the pull request. The server filters completions by checking if the label starts with the typed text. With "[WARNING]" as the label, a user would need to type [ or [W to trigger this completion, not WA.

To fix this and match the intended behavior, the label should be "WARNING". The insertText property will still correctly insert the full [WARNING] block.

Suggested change

	CompletionItem warning = new CompletionItem("[WARNING]");
	CompletionItem warning = new CompletionItem("WARNING");
