AdminThemeUikit admin-custom.css --pw-button-muted-color: Remove double semicolon

[howdytom]

A minor cosmetic CSS fix for --pw-button-muted-color variable in wire/modules/AdminTheme/AdminThemeUikit/themes/default/admin-custom.css

Remove double semicolon. Instead of

--pw-button-muted-color: light-dark(var(--pw-blocks-background), var(--pw-text-color));;

Replace with

--pw-button-muted-color: light-dark(var(--pw-blocks-background), var(--pw-text-color));
