Removed deprecated tilde in imports

[KDNeufeld]

As of Angular 13, tilde imports has been deprecated and removed in the Sass loader. This project no longer works with newer versions of Angular. ref: https://github.com/angular/components/commit/f2ff9e31425f0e395e6926bcaf48f876688000d8

I was getting errors following the directions on the Getting Started documentation.

X [ERROR] Can't find stylesheet to import.

I was able to resolve the issue by simply removing the ~ in the path of a few import statements.

styles.scss

$bcgov-font-path: "@bcgov/bootstrap-theme/dist/fonts/";
@import "@bcgov/bootstrap-theme/dist/scss/bootstrap-theme";
@import "@bcgov/bootstrap-theme/dist/scss/common"; 

/* Importing Bootstrap SCSS file. */
@import "bootstrap/scss/bootstrap";

I updated the documentation to reference v1.1.4, hopeful a new release would be made available soon.
