Unable to skip forward or back `.aac` files

### Description

When `.aac` files are imported the app cannot skip them in time. When I import an `.aac` file through the app I expect I will be able to control the playback via skip buttons. However app fails to do so with the `Unable to seek. File headers appear to be invalid.` toast message.

The code responsible for displaying the message is here.

Also, there are [reports on Stack](https://serverfault.com/questions/1108600/nginx-byte-range-requests-are-enabled-but-pocket-casts-still-reports-invalid-hea) of our app not functioning well in the similar manner.

### Step-by-step reproduction instructions

Have some `.aac` files on a device or in the cloud where you can access them from a device. You can use sample `.aac` files from [here](https://filesamples.com/formats/aac) or use [this sample](https://github.com/Automattic/pocket-casts-android/files/13950090/sample1.zip).

1. Go to `Profile`.
2. Go to `Files`.
3. Import an `.aac` file.
4. Play it back.
5. Try to control it with the skip buttons.

Reproduce the issue with the linked sample .aac file by following the Profile > Files import and playback steps. Start at modules/services/repositories/src/main/java/au/com/shiftyjelly/pocketcasts/repositories/playback/SimplePlayer.kt lines 130-137, then trace the failed seek path. Done means the skip buttons seek within imported .aac files without showing the invalid-headers toast.
