Using vs-code to edit files in blob storage changes the files content-type.

[Zliide-Nicklas]

We have some files located in blob storage, from time to time we need to edit in some of these.
But when we are saving the file in vs-code, the files content-type is changed in the blob storage from "application/javascript; charset=UTF-8" to "application/javascript".
Could be nice to be able to specify the content-type of a file when changes are being uploaded or at least if the content-type wasn't changed when uploading the changes of file.
