Updating libgraph-perl

[Andrius Merkys]

Hello,

Upstream has just released libgraph-perl 0.9726 fixing a bug [1]. I 
would like to have this fix in bookworm. I could update libgraph-perl 
myself, but I noticed the repository on salsa contains all upstream 
commits, and I do not know how to import them. I usually do

gbp import-orig --pristine-tar --uscan

but this imports just the tarball. Could someone knowledgeable of the 
update procedure do so?

Best,
