fix(font-family): fallback coming from tokens was badly formatted (#30703)

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
- The variables when being generated from the tokens were causing the
fallback to `$ion-font-family` to be with invalid format:
    ```
    $ion-font-family: var(
      --token-font-family,
"-apple-system, system-ui, " Segoe UI ", Roboto, Helvetica, Arial,
sans-serif, " Apple Color Emoji ",
      " Segoe UI Emoji", " Segoe UI Symbol "",
      sans-serif
    );
    ```
- Additionally the command to generate the css from the tokens, was not
prepared to run on windows machines.
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- Removed the added quotes to the variable coming from the tokens:
    ```
    $ion-font-family: var(
--token-font-family, -apple-system, system-ui, "Segoe UI", Roboto,
Helvetica, Arial, sans-serif,
      "Apple Color Emoji", "Segoe UI Emoji", "Segoe UI Symbol"
   );
    ```
- Changed the command `build.tokens` to run on windows
- Generated a new version of `ionic.vars.scss`
