Clone specific repo tag instead of HEAD during deployment #1456

Hello,
I was wondering if this is a bug, feature or maybe I'm just missing something. I thought that using --version option within deploy command will clone a specific tag from repository with name corresponding to --version value. Instead, this value is used only to version the docker image. In all cases always the HEAD is cloned regardless the --version value. I have investigated the source code and find no reference to repo tags just the "rev-parse HEAD" mentions, e.g. in module Kamal::Commands::Builder::Clone without ability to configure it.
I'm asking about tag clone feature because I have always used Capistrano for deployment and according to sentence "Kamal basically is Capistrano for Containers" I thought I was in right place.
Some example for reference:

> kamal redeploy -H -d staging --version 1.0.0-rc.1

...
INFO [aa4f561e] Running /usr/bin/env git -C /tmp/kamal-clones/my-app-64249e376ff9a clone /home/me/projects/my-app-project --recurse-submodules as me@localhost
INFO [aa4f561e] Finished in 0.120 seconds with exit status 0 (successful).
INFO [59139fc4] Running /usr/bin/env git -C /tmp/kamal-clones/my-app-64249e376ff9a/malina/ status --porcelain as me@localhost

INFO [b8ee382c] Running /usr/bin/env git -C /tmp/kamal-clones/my-app-64249e376ff9a/my-app-project/ rev-parse HEAD as me@localhost
...

I hope that I'm missing something.

The only workaround I found is to checkout the desired tag before the deployment command.
