Cannot format zeek-7 IDs in global scope

[bbannier]

zeek-7 changed the way global IDs are written from GLOBAL::XYZ to ::XYZ. This syntax is not supported by e.g., zeek-format.

type r: record { };

event zeek_init()
	{
	local x: ::r;
	}

$ zeek-format foo.zeek
cannot parse line 5, col 9: ": :"
type r: record { };

event zeek_init()
        {
        local x : : : r;
        }

I filed a PR to fix the grammar part of this, zeek/tree-sitter-zeek#28. This still requires changes to zeek-format which even with the adjusted grammar seems to insist on inserting too many spaces.
