Fixing Issue with Power BI and Excel #531

[cmendible]

This pull request removes the creation of pivot tables for recommendations in the Excel report generation process. The related functions and logic for tracking the last row of recommendations and generating the pivot tables have been deleted, simplifying the codebase.

Removal of Recommendations Pivot Table Feature

• Deleted the renderRecommendationsPivotTables function and all logic related to creating pivot tables for recommendations in the Excel report, including the use of lastRow to determine data range (internal/renderers/excel/excel.go, internal/renderers/excel/recommendations.go) [1] [2] [3].

Code Simplification

• Updated the renderRecommendations function to no longer return the last row index, as it is no longer needed for pivot table creation (internal/renderers/excel/recommendations.go) [1] [2].
• Removed unused imports (fmt, strconv) that were only required for pivot table creation (internal/renderers/excel/recommendations.go).# Description
