Migrate CI workflows from bash scripts to Rust dependency-installer binary

[Copilot]

Replaces bash-based dependency installation in GitHub Actions workflows with the dependency-installer Rust binary (from #113). Removes obsolete bash scripts.

Changes

Updated 3 workflow files to use unified installation:

• .github/workflows/test-e2e-provision.yml
• .github/workflows/test-e2e-config.yml
• .github/workflows/test-lxd-provision.yml

# Before: Multiple bash script calls
- name: Install and configure LXD
  run: ./scripts/setup/install-lxd-ci.sh
- name: Install OpenTofu
  run: ./scripts/setup/install-opentofu.sh

# After: Single binary invocation
- name: Install dependencies
  run: |
    cargo build -p torrust-dependency-installer --bin dependency-installer
    cargo run -p torrust-dependency-installer --bin dependency-installer -- install

Removed bash scripts from scripts/setup/:

• install-lxd-ci.sh
• install-opentofu.sh
• install-ansible.sh

Updated scripts/setup/README.md with migration notice documenting the new approach.

Closes #119
Part of #112 (E2E test execution refactor)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• 192.0.2.1
  • Triggering command: ssh -i /nonexistent/key -p 22 -o ConnectTimeout=5 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null testuser@192.0.2.1 echo 'SSH connected' (packet block)
  • Triggering command: ssh -i /nonexistent/key -p 22 -o StrictHostKeyChecking=no -o ConnectTimeout=5 -o UserKnownHostsFile=/dev/null testuser@192.0.2.1 echo 'SSH connected' (packet block)
• get.opentofu.org
  • Triggering command: curl --proto =https --tlsv1.2 -fsSL REDACTED -o /tmp/install-opentofu.sh (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_description>Parent Epic: #112 - Refactor and Improve E2E Test Execution
Depends On: #113 - Create Dependency Installation Package for E2E Tests

Summary

Update GitHub Actions workflows to use the new dependency-installer binary instead of bash scripts, and remove the obsolete bash scripts from scripts/setup/. This completes the migration from bash-based dependency management to the Rust-based solution.

Objectives

• Update all GitHub Actions workflows to use dependency-installer binary
• Remove obsolete bash scripts from scripts/setup/
• Update documentation to reference the new dependency installation method
• Verify CI workflows pass with the new approach

Workflow Files to Update

The following 3 GitHub Actions workflow files need updates:

1. .github/workflows/test-e2e-provision.yml

   • Currently uses: ./scripts/setup/install-lxd-ci.sh
   • Currently uses: ./scripts/setup/install-opentofu.sh

2. .github/workflows/test-e2e-config.yml

   • Currently uses: ./scripts/setup/install-ansible.sh

3. .github/workflows/test-lxd-provision.yml

   • Currently uses: ./scripts/setup/install-lxd-ci.sh
   • Currently uses: ./scripts/setup/install-opentofu.sh

Note: Other workflow files do NOT use bash scripts and do not need modification.

Workflow Changes

Update workflows to use the Rust binary:

- name: Install dependencies
  run: |
    cargo build --bin dependency-installer
    cargo run --bin dependency-installer install

Acceptance Criteria

• Pre-commit checks pass
• All 3 workflows updated to use dependency-installer
• Bash scripts removed from scripts/setup/
• CI workflows pass with new approach
• Documentation updated

Time Estimate

2-4 hours
