fix(sass): use map.has-key instead of map-has-key to avoid deprec…

…ation warnings

Error:
- Deprecation Warning: Global built-in functions are deprecated and will be removed in Dart Sass 3.0.0.
Use map.has-key instead.

Reason:
- We are deprecating the global functions now that the module system has been available for several years in sass: modules.
While Dart Sass 2.0.0 will be released soon with various smaller breaking changes, we don’t expect to remove Sass @import rules or global built-in functions until Dart Sass 3.0.0, which will be released no sooner than two years after Dart Sass 1.80.0.

Solution:
- Import the `sass:map` module to use the functions: `@use "sass:map"`
You can't do these imports in the main `styles.scss` file, it doesn't work, you must do it in the file you are going to use it in.
- Use `map.has-key` instead of `map-has-key()`:
From `map-has-key($breakpoints, $breakpoint)` to `map.has-key($breakpoints, $breakpoint)`.
