Problem with v:asset.script without path

[jurajsulek]

PHP 8.1
we use v:asset.script without path just with content. E.g.
<v:asset.script name="...">
some code
</v:asset.script>

in FluidTYPO3\Vhs\Service\AssetService->extractAssetContent there ist:
$fileRelativePath = dirname($assetSettings['path']);
which trows an error because $assetSettings['path'] is null.

simple fix is to change the lines:
$fileRelativePath = dirname($assetSettings['path']);
$absolutePathAndFilename = GeneralUtility::getFileAbsFileName($fileRelativePathAndFilename);

to
if($fileRelativePathAndFilename) {
$fileRelativePath = dirname($assetSettings['path']);
$absolutePathAndFilename = GeneralUtility::getFileAbsFileName($fileRelativePathAndFilename);
}
