fix: add missing SASS entry point

[santam85]

This change would allow importing the sass files in Angular projects in the following fashion:
@import "~angular-calendar/scss/angular-calendar";
That is beneficial for plugins trying to find the critical path CSS, and allows to avoid having to hardcode a relative path to the node_module, simplifying adoption in monorepos with multiple projects.

Fixes #1596 and errors like:

SassError: Can't find stylesheet to import.
   ╷
12 │ @import "~angular-calendar/scss/angular-calendar";
   │         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   ╵
  src/styles.scss 12:9  root stylesheet

Alternatively, this can be extended to all scss files by adding instead:

    "./scss/*" : {
      "sass": "./scss/*"
    },

EDIT
After some research and testing, I updated the PR to use the alternative approach shown above, looks like it's the one that has the best compatibility.

Hello @santam85 & @mattlewis92
i was using this in v0.28.28: @import '~angular-calendar/scss/angular-calendar.scss';, but it's not working in v0.31.1
any idea why ?

I think it's because angular dropped support for the leading ~, try @import 'angular-calendar/scss/angular-calendar.scss'; instead
