Update the template generator for RSL-RL

[ClemensSchwarke]

Description

This PR adds Distillation to the list of available algorithms for RSL-RL. It also updates the config templates to RSL-RL version 5. This is a reimplementation of #5117 but now targeting develop.

Distillation default entry point missing

When a project is generated with RSL-RL Distillation but without PPO, registration exposes only rsl_rl_distillation_cfg_entry_point, while the standard train and play commands request rsl_rl_cfg_entry_point, causing configuration loading to fail with Could not find configuration for the environment.

Algorithm expectations omit Distillation

Adding DISTILLATION changes the discovered RSL-RL single-agent algorithms to ["DISTILLATION", "PPO"], but the checked-in discovery tests still expect only ["PPO"], causing test_get_algorithms_per_rl_library_filters_by_workflow_type to fail.

Greptile Summary

The PR extends generated RSL-RL projects with Distillation and updates their configuration templates for RSL-RL v5.

• Adds Distillation algorithm discovery and a corresponding runner configuration template.
• Adds explicit observation-group mappings to generated PPO configurations.
• Generates the Distillation runner class entry point and updates the CLI capability table.

Confidence Score: 4/5

The missing default Distillation entry point and stale test expectations should be fixed before merging.

Distillation-only generated projects fail configuration loading through the standard train and play commands, and the changed discovery result breaks checked-in template-generator assertions.

Important Files Changed

Filename	Overview
tools/template/common.py	Adds Distillation to single-agent discovery but leaves explicit discovery-test expectations stale.
tools/template/templates/agents/rsl_rl_distillation_cfg	Adds a v5-style Distillation runner configuration consistent with existing repository configurations.
tools/template/templates/agents/rsl_rl_ppo_cfg	Adds actor and critic observation-group mappings matching existing RSL-RL v5 configurations.
tools/template/templates/tasks/__init__task	Resolves the Distillation class name correctly, but algorithm-only projects lack the default configuration key used by training and playback.
tools/template/cli.py	Improves algorithm display wrapping and advertises RSL-RL distributed-training support.

thanks for this update! could you also update the template generator tests to take into consideration the new changes?
