Subject: [PATCH] Fix repository adoption on Windows (#21646) (#21651)

Backport #21646

A bug was introduced in #17865 where filepath.Join is used to join
putative unadopted repository owner and names together. This is
incorrect as these names are then used as repository names - which shoud
have the '/' separator. This means that adoption will not work on
Windows servers.

Fix #21632
