chore!: remove deprecated --branch and --template flags from samples command

[zimeg]

Changelog

We removed the deprecated --branch and --template flags from the samples command to now prefer the create command when repository details are known.

Summary

🪓 This PR removes the hidden --branch and --template flags from the samples command, along with the deprecation warning and dead flag forwarding logic. The create command should be used directly when a specific template or branch is needed.

Requirements
