Add category name in ID property for extension row in Special:Version page

Extensions can belong to multiple different categories. When listing them in
the Special:Version page each entry is surrounded with HTML element with
ID property "mw-version-ext-{NAME}". This causes generation of duplicate
ID values, which is against W3C rules.
To preserve valid and compliant HTML while retaining ID values, change the
ID pattern to "mw-version-ext-{CATEGORY}-{NAME}".
