Pull request overview

This PR fixes a bug where markdown formatting (such as bold **text**) inside square brackets was not being rendered correctly when there was no corresponding reference definition. The fix changes the behavior to recursively process the markdown content within brackets rather than treating it as plain text.

Key changes:

• Modified appendMarkdownReference function to recursively parse markdown within unresolved reference links
• Changed from rendering unresolved references as plain text to processing their individual components (LINK_TEXT and LINK_LABEL)

Variable shadowing: The variable name linkText is already used in this function scope (line 167). Consider using a different name like linkTextNode to avoid confusion and improve code clarity. The shadowed variable has type List<ASTNode>? while this new variable has type ASTNode?, which makes the distinction even more important.

Suggested change

	val linkText = node.findChildOfType(MarkdownElementTypes.LINK_TEXT)
	if (linkText != null) {
	buildMarkdownAnnotatedString(content, linkText, annotatorSettings)
	val linkTextNode = node.findChildOfType(MarkdownElementTypes.LINK_TEXT)
	if (linkTextNode != null) {
	buildMarkdownAnnotatedString(content, linkTextNode, annotatorSettings)

The new behavior for rendering markdown inside brackets when no reference is found lacks test coverage. Consider adding a test case in sample/android/src/screenshotTest/kotlin/com/mikepenz/markdown/ui/m3/LinkTests.kt (and the m2 equivalent) that includes examples like [**bold text**] or [*italic*] to verify the fix works as intended and prevent future regressions.
