fix: Insert pub(crate) after doc comments and attribute macros

[TopGunSnake]

Fixes #12790

Original behavior was to insert pub(crate) at the first_child_or_token, which for an item with a comment or attribute macro, would put the visibility marker before the comment or macro, instead of after.

This merge request alters the call to find the node with appropriate SyntaxKind in the children_or_tokens. It also adds a test case to the module to verify the behavior. Test case verifies function, module, records, enum, impl, trait, and type cases.

[TopGunSnake]

Need verification that the cases added are sufficient for all known cases to add a pub(crate).
