The linter cannot understand this bit of JSON

While trying to lint json/item_groups.json, I have encountered the following bit of JSON which the linter cannot understand:

{ "type" : "item_group", "id" : "razorclaw_nest", "subtype" : "distribution", "entries":[ {"item":"razorclaw_roe", "repeat": [ 1,6 ]} ] },
Linter cannot understand “repeat”:

Is this a bug?

It’s a bug because the author meant to use “count”: [1, 6] instead. doc/ITEM_SPAWN.md has all the information about item groups.
