* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

title: Aplica un estilo hasta que se cumpla una condición con @while

# --description--
La directiva `@while` es una opción con funcionalidad similar al bucle `while` de JavaScript. Crea reglas CSS hasta que se cumpla una condición.
El desafío `@for` dio un ejemplo para crear un sistema de cuadrícula (grid) simple. Esto también puede funcionar con `@while`.
```scss
$x: 1;
@while $x < 13 {
.col-#{$x} { width: 100%/12 * $x;}
$x: $x + 1;
}
```
Primero, define una variable `$x` y establécela a 1. A continuación, utiliza la directiva `@while` para crear el sistema de cuadrícula *while* `$x` sea menor que 13. Después de configurar la regla CSS para `width`, `$x` se incrementa por 1 para evitar un bucle infinito.
# --instructions--
Usa `@while` para crear una serie de clases con diferentes `font-sizes`.
Debe haber 5 clases diferentes desde `text-1` hasta `text-5`. Luego ajusta `font-size` a `15px` multiplicado por el número de índice actual. ¡Asegúrate de evitar un bucle infinito!
# --hints--
El código debe usar la directiva `@while`.
```js
assert(code.match(/@while /g));
```
El código debe utilizar una variable de índice que comience en un índice de 1.
```js
assert(code.match(/\$.*:\s*?1;/gi));
```
Tu código debe incrementar la variable contador.
```js
assert(code.match(/\$(.*)\s*?:\s*\$\1\s*\+\s*1\s*;/gi));
```
Tu clase `.text-1` debe tener un `font-size` de `15px`.
```js
assert($('.text-1').css('font-size') == '15px');
```
Tu clase `.text-2` debe tener un `font-size` de `30px`.
```js
assert($('.text-2').css('font-size') == '30px');
```
Tu clase `.text-3` debe tener un `font-size` de `45px`.
```js
assert($('.text-3').css('font-size') == '45px');
```
Tu clase `.text-4` debe tener un `font-size` de `60px`.
```js
assert($('.text-4').css('font-size') == '60px');
```
Tu clase `.text-5` debe tener un `font-size` de `75px`.
```js
assert($('.text-5').css('font-size') == '75px');
```
