Address deprecation warnings from SASS breaking changes

We are currently seeing SASS errors such as:

DEPRECATION WARNING: blue() is deprecated. Suggestion:
       
       color.channel($color, "blue", $space: rgb)
       
       More info: https://sass-lang.com/d/color-functions

It appears this is coming from an upstream breaking change in Sass, per jgthms/bulma#3907.

We are waiting for the new release of Bulma that solves this deprecation.
