Describe the feature

The editor does not apply correct syntax highlighting for multiline JSDoc definitions.

Current implementation marks all text of a JSDoc definition after a line break as a regular comment. It should be highlighted just like it is when written in a single line.

If applicable, add mockups / screenshots to help present your vision of the feature

Are you sure this is valid jsdoc? (Apologies for my ignorance if so):

/**
* @typedef {{fizz: fizz, buzz: buzz}}
* @typedef {{
* fizz: fizz
* buzz: buzz
}}
*/

VSCode also seems to highlight this incorrectly:

The upstream tree-sitter-jsdoc seems to be puking on the {{ at the end of the line too.

# tree-sitter parse a.jsdoc
(document [0, 0] - [6, 0]
  (tag [1, 2] - [1, 10]
    (tag_name [1, 2] - [1, 10]))
  (ERROR [1, 11] - [4, 2]))
a.jsdoc	   0.04 ms	  1937 bytes/ms	(ERROR [2, 11] - [5, 2])

If this is valid syntax, please file that upstream.
