Bump Sass and migrate / to math.div()

[TylerVigario]

Fix for #1217: Using / for division was recently deprecated in Sass.

I've updated the source to use math.div() and moved to Dart Sass (version 1.33).

Use fork from @kikyous above.

@kikyous, @TylerVigario after installing the fork with the fix I'm getting the following error:

Error: Invalid CSS after "...     floor(math": expected expression (e.g. 1px, bold), was ".div($grid-gutter-w"
        on line 370 of ../../../../../../.rbenv/versions/2.7.4/lib/ruby/gems/2.7.0/bundler/gems/bootstrap3-sass-bbd592141451/assets/stylesheets/bootstrap/_variables.scss
        from line 8 of ../../../../../../.rbenv/versions/2.7.4/lib/ruby/gems/2.7.0/bundler/gems/bootstrap3-sass-bbd592141451/assets/stylesheets/_bootstrap.scss

which seems to be coming from this line. Any ideas on how to fix the issue? I'm using ruby 2.7.4 and rails in version 6.1.4.1.

It is a npm package,not a ruby gem.

@kikyous, @TylerVigario Thanks for the quick response. npm is just a way of making the package available to use in projects. According to the README of both the forked version and the original one it's possible to use it with ruby on rails. That's they way that I'm using it in the project that I'm working on and it's causing the issue that I've described in my previous comment. Most probably I'll try to experiment with the fork locally and will try to pin point the issue. If you come up with any idea why this issue is happening then I would be grateful.

@szysza math.div is available only in Dart Sass v1.33 and later. Can you confirm you are using Dart Sass with at least version 1.33?

@kikyous Thank you for forking the repo. Would you mind opening the issue tab on your repo in case of problems like this in the future?
