[Bug]: `ThemeProperties::basePath()` returns parent theme's path instead of child theme's

[o-samaras]

Description of the bug

When having a child theme, ThemeProperties::basePath() returns the parent theme's path instead of the child theme's.

Reproduction instructions

1. Create a child theme
2. Initialize the package properties with

       $properties = ThemeProperties::new('child-theme-name');
       $package = Package::new($properties);

3. Boot the package
4. Use ThemeProperties::basePath()

Expected behavior

If parent theme (let's call it parent-theme) has a child theme (let's call it child-theme), then when calling ThemeProperties::basePath() from within child-theme I expect to see a path of .../wp-content/themes/child-theme. Instead I get .../wp-content/themes/parent-theme.

Environment info

Package version: 1.6.0 Browser: N/A System: Windows 10

Relevant log output

No response

Additional context

This is caused because properties are initialized using get_template_directory() instead of get_stylesheet_directory().
