Max Wipfli cb5a50d3f7 LibGUI: Fix off-by-one error in Lexer tokens
This changes the INI and GML lexers to conform to the now-fixed
rendering of syntax highlighting spans in GUI::TextEditor.

The other user of GMLToken::m_end, GMLAutocompleteProvider, has been
modified to take into account that end position columns have been
incremented by one.
