The very first example from the documentation doesn't work

**Glide Version**: 4.12.0

**Integration libraries**: N/A

**Device/Android Version**: Pixel_3a_API_28_x86 (Emulator)

**Issue details / Repro steps / Use case background**:

It's my first time with Glide. Haven't tried any other image loading library ever.

I have tried the first example the `README` provides. But it didn't work.

```kotlin
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val image = findViewById(R.id.image)

val url = "http://goo.gl/gEgYUd"

Glide.with(this).load(url).into(image)
}
```
It shows nothing on the screen. And the logs aren't of much help to me.

``` ruby

```

I guess the `Cleartext HTTP traffic to goo.gl not permitted` log is the root cause of the problem. It has something to do with `http` and `https`.

After some research, I converted the `url` into `uri` with the `https` scheme.

```kotlin
val url = "http://goo.gl/gEgYUd"
val uri = url.toUri().buildUpon().scheme("https").build()
Glide.with(this).load(uri).into(image)
```

And it worked perfectly.

I am wondering whether this issue is specific to my build environment? If so then what's the problem exactly? Or it happens with other developers as well? If so then why does the documentation use this as the first example?

**Glide load line / `GlideModule` (if any) / list Adapter code (if any)**:
```java
Glide.with(this).load(uri).into(image)
```

**Layout XML**:
```xml

```
