fix: use markdown blockquote in --reply-to instead of wiki markup (#34)

fix: use markdown blockquote instead of wiki markup in --reply-to

The reply-to feature was using Jira wiki markup ({quote}...{quote}) to
quote the original comment, but the body is parsed as Markdown and
converted to ADF. This caused the literal text "{quote}" to appear in
the rendered comment.

Switch to Markdown blockquote syntax (> prefix) which the parser
correctly converts to ADF blockquote nodes.
