Describe the bug

Module membership declarations are not support in the grammar

Requirements

• I've read and understood the Contributing guidelines and have done my best effort to follow them.
• I've read and agree to the Code of Conduct.
• I've searched for any related issues and avoided creating a duplicate issue.

To Reproduce

Grammar does not support module membership declarations which prevents a highlighting query from targeting them.

module foo;

Which currently parses as the following (notice the ERROR)

(expression_statement  
    (qualified_identifier  
      (identifier)) 
    (ERROR 
      (identifier)))

Expected behavior

I expect the module membership declarations to parse properly.
