[Admin Reskin] Active filter tab color on “Add Themes” and “Add Plugins” pages does not follow the new admin color scheme

[hbhalodia]

Description

On a WordPress site using the new admin reskin, the active filter tab color on the “Add Themes” and “Add Plugins” pages still uses the old admin color scheme instead of the updated design color.

When selecting any filter tab (for example, Featured), the active tab highlight does not match the new admin UI colors and appears with the legacy styling. The active state should follow the new admin color scheme introduced with the admin reskin.

Steps to Reproduce

1. Log in to the WordPress dashboard.
2. Navigate to Dashboard → Plugins.
3. Click Add Plugin.
4. Select the Featured tab (or any other filter tab).
5. Observe the active tab color.

See the screenshots attached.

To Validated, See the settings -> privacy page, You will notice new active tab color.
