tdf#155877 Fix broken links in Shapes and Page Menu help pages

Correct typo in /text/simpress/02/10080000.xhp so that pressing F1 opens the correct help page for Shapes > Insert > Curves and Polygons > Polygon (45 degree).

Add HID bookmark in /text/shared/02/blockarrows.xhp so that pressing f1 opens the correct help page for Shapes > Insert > Block Arrows > Up and Down Arrow Callout.

Add correct HID bookmark in /text/shared/menu/save_image.xhp so that pressing F1 opens the correct help page for Page > Save Background Image.

Add HID bookmark to /text/simpress/01/13050000.xhp so that pressing F1 opens the correct help page for Shapes > Convert.
