Describe the issue

I've updated SASS to 1.56 and get the following deprecation warning

Deprecation Warning: $weight: Passing a number without unit % (100) is deprecated.

To preserve current behavior: $weight * 1%

More info: https://sass-lang.com/d/function-units

    ╷
201 │   @return mix(rgba($foreground, 1), $background, opacity($foreground) * 100);
    │           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    ╵
    node_modules/bootstrap/scss/_functions.scss 201:11            opaque()
    node_modules/bootstrap/scss/mixins/_table-variants.scss 4:28  table-variant()
    node_modules/bootstrap/scss/_tables.scss 147:3                @import
    node_modules/bootstrap/scss/bootstrap.scss 20:9               @import

Reduced test cases

Add unit (100%)
@function opaque($background, $foreground) { @return mix(rgba($foreground, 1), $background, opacity($foreground) * 100%); }
