I removed the bg-white and dark:bg-gray-800 from the relevant images, but left it on the wrench. As noted in the ticket above, this is just a minor tweak that's been bothering me for a while.

Copilot summary

This pull request primarily focuses on modifying the CSS classes of various img elements in the PluginStoreItem.tsx and MultiSelectPop.tsx files. The changes remove the bg-white class from these elements, which previously set the background color of the images to white.

Here are the key changes:

• client/src/components/Plugins/Store/PluginStoreItem.tsx: The bg-white class is removed from the img element in the PluginStoreItem function. This change affects the display of the plugin icons.
• client/src/components/ui/MultiSelectPop.tsx: The bg-white class is removed from two img elements in the MultiSelectPop function. The first change affects the display of the selected values' icons, and the second change affects the display of the option icons. [1] [2]
