Update changelog for hotfix

On a new installation, Stash will default to 'blobs' (which relative to the CWD of /, becomes '/blobs').
In our recommended installation, this is NOT mapped and as a result will NOT be persistent across the container being removed or updated.

So by default, we are populating blob data which will be deleted, likely leaving to some confused new users.
This should also be noted for existing installations to make this a persistent path.
