## Description

When adding a PDF file to `tx_bootstrappackage_tab_item`'s media field the `link` field is not showing up so it's impossible to add a link an PDF file.

The issue seems to be in `Configuration/TCA/tx_bootstrappackage_tab_item.php`, ['columns']['media']['overrideChildTca'] only checking for types `\TYPO3\CMS\Core\Resource\File::FILETYPE_IMAGE` and `\TYPO3\CMS\Core\Resource\File::FILETYPE_VIDEO`.

Adding
```
\TYPO3\CMS\Core\Resource\File::FILETYPE_APPLICATION => [
'showitem' => '
--palette--;;extendedBasicOverlayPalette,
--palette--;;filePalette',
],
```
fixed the issue for me. Consider adding `\TYPO3\CMS\Core\Resource\File::FILETYPE_TEXT` or `\TYPO3\CMS\Core\Resource\File::FILETYPE_UNKNOWN` so these can be linked too.

## Steps to Reproduce

1. Create a `Tab` content element.
2. Add a new tab item.
3. Add a PDF file to the `media` field.

### Expected behavior

`link` field showing.

### Actual behavior

No `link` field showing.
