error messages from collectors

using collectors you often create error messages which are not tight to a specific file

e.g. as described in https://tomasvotruba.com/blog/how-to-measure-your-type-coverage/
you get a output of:

 vendor/bin/phpstan analyze  -c phpstan.neon.dist
 355/355 [============================] 100%

 ------ ---------------------------------------------------------------------------------------------------------
  Line   N/A
 ------ ---------------------------------------------------------------------------------------------------------
  -1     Out of 1295 possible param types, only 57 % actually have it. Add more param types to get over 99 %
  -1     Out of 1582 possible return types, only 32 % actually have it. Add more return types to get over 99 %
  -1     Out of 873 possible property types, only 0 % actually have it. Add more property types to get over 99 %
 ------ ---------------------------------------------------------------------------------------------------------

as you can see, in this case we get a error-line reported as -1 and a file of N/A.

I think for error messages which are not related to a file, the result table should not print out a line - as it doesn't make sense to print a line number, when no filename is known.

therefore I would prefer a result table like

 vendor/bin/phpstan analyze  -c phpstan.neon.dist
 355/355 [============================] 100%

 ---------------------------------------------------------------------------------------------------------
    Out of 1295 possible param types, only 57 % actually have it. Add more param types to get over 99 %
    Out of 1582 possible return types, only 32 % actually have it. Add more return types to get over 99 %
    Out of 873 possible property types, only 0 % actually have it. Add more property types to get over 99 %
 ---------------------------------------------------------------------------------------------------------

for this kind of errors

The documentation https://phpstan.org/developing-extensions/collectors states this:

Because these custom CollectedDataNode rules are executed out of context, the reported errors should specify the file and line to report:

So what https://tomasvotruba.com/blog/how-to-measure-your-type-coverage/ is doing is invalid usage I'd say. But I understand it might be useful...
