Fix invalid CSS property in ImageSliderSingle.module.scss

[coderabbitai]

Description

The CSS rule .projectImageSliderContentText in src/features/user/TreeMapper/components/ImageSliderSingle/ImageSliderSingle.module.scss (line 14-15) uses bottom: 10 which is invalid because:

1. It's missing a unit (should be 10px or another length unit)
2. The bottom property only works with positioned elements (position: relative/absolute/fixed)

If the intent is to add spacing at the bottom of the text, consider using margin-bottom or padding-bottom instead.
