Bump sassc-embedded from 1.70.1 to 1.80.1

Note: Since we update to 1.80.1 deprecation warnings are appear when execute the assets:precompile command.
In order to silence this deprecation, we add silence_deprecation option in sass.rb initializer.

The code has also been updated to remove the deprecation warnings that appeared related to the function
darken(), lighten() and "Using / for division" instead of the function calc().

Bumps [sassc-embedded](https://github.com/sass-contrib/sassc-embedded-shim-ruby) from 1.70.1 to 1.80.1.
