Updated dependency

I am trying to update terraform module used in my project, the source file is like this
source = "git::ssh://[email protected]/private/infra-live.git//modules/btg/first-module?ref=dc7c47554614c3d3d3065a45e020fc7f44adbscx"

Project is a monorepo with something like this

.
live/
  /something
      /another folder
module/
   /btg
       /first_module
       /second_module

git ls-remote result

dc7c47554614c3d3d3065a45e020fc7f44adbscx	refs/tags/first-module-v1.1.0
