Change Navigation Button Appearance on Plugin Screenshot Gallery

[iambherulal]

I propose improving the design and appearance of the navigation buttons on the plugin screenshot gallery. Currently, the buttons do not align with the modern design standards and user experience expectations.

Suggested Changes

• Update the button styles to match the overall aesthetic of the WordPress Plugin Directory.

Benefits

• Enhanced visual appeal of the plugin directory.

Note
I am submitting a diff file for the CSS changes I’ve made. Since I don't have ways to check the changes in realtime, I located the file based on the class name and added the necessary CSS changes.
