LPS-52282 - Documents and Media button 'Open in MS Office' causes exception

Hi Jon,

Attached is an update for https://issues.liferay.com/browse/LPS-52282.

I discovered this issue when I was working on the jquery migration for open_in_ms_office.ftl.

There is a change in the menu-item taglib that fixes the display of the icon.  I didn't break it off into a separate fix because this is the only place a JavascriptMenuItem is used and it is very minor.

Please let me know if there are any issues.

Thanks!
