fix: Wrong Type Definition, "rowHeaders" of IGridOptions index.d.ts

[BillionaireDY]

Version

3.6.0

Development Environment

mac, chrome

Current Behavior

as is

    interface IGridOptions {
      ...
        rowHeaders?: IRowHeadersOptions; 
      ...
    }

to be

    interface IGridOptions {
      ...
        rowHeaders?: string[] | IRowHeadersOptions[]; 
      ...
    }

Expected Behavior

The rowHeaders of IGridOptions of index.d.ts is defined differently from the document.
