[FEATURE REQ] Throw FileNotFoundException when blob does not exist

**Is your feature request related to a problem? Please describe.**
When building an _InputStream_ with _Files.newInputStream(myPath)_ from a Azure Blob Storage using _azure-storage-blob-nio_, if the blob does not exist, the exception thrown by _AzureFileSystemProvider_ is _IOException_ with the message:
`Path either does not exist or points to a directory.Path must point to a file. Path: my_directory/my_path`

**Describe the solution you'd like**
As according to the [Blob API errors](https://learn.microsoft.com/en-us/rest/api/storageservices/blob-service-error-codes), there is a _BlobNotFound_ error, which is obviously 404 HTTP code, it would be quite normal to expect a _FileNotFound_ exception in return when the blob does not exist.

**Describe alternatives you've considered**
Solution I have used is to parse the error message and throw a _FileNotFoundException_ if it contains a part of the message mentioned above and if not rethrow the _IOException
