`startColumn must be greater than or equal to 1` message should report offset for error

Beginne mit dem Validierungsfehler in upload-lib.js in den Zeilen 201 und 251 und verfolge anschließend, wie upload-sarif-action.js Schemafehler meldet. Reproduziere den verknüpften SARIF-Upload-Fehler und ermittle, wo der fehlerhafte Offset und der umgebende Inhalt sichtbar gemacht werden können. Als erledigt gilt, wenn ungültige Werte für startColumn und endColumn verwertbare Positionsdetails statt nur der Mindestanforderungsnachricht liefern.

Ideally when reporting issues, at a minimum, a line / character offset should be reported, and unless there's a risk of binary output breaking things, a substring showing the offending content in context would be appreciated. (I'm sure I can find the item(s), but I shouldn't have to search through an 850k file to find the problem.

Fwiw, here's the relevant snippet, and it'd be really much nicer if I didn't have to try to search for it (especially because I can't actually search for startColumn:0, I have to remember to search for startColumn":0 -- and if I'm less familiar w/ the json -- which anyone other than me would be -- then I wouldn't know if I need to consider optional whitespace..).
