ci: add network-launcher bump and promote workflows

[lwshang]

Summary

Adds two GitHub Actions workflows for managing the icp-cli-network-launcher version pin, and moves the pin file out of the test crate to signal its broader role.

• bump-network-launcher.yml — workflow_dispatch with a required version input. Verifies the release tag exists in dfinity/icp-cli-network-launcher, writes the stripped version to the pin file, and opens a PR via the pr-automation-bot-public App.
• promote-network-launcher.yml — fires on push to main when the pin file changes. Reads the version, prepends v, and dispatches promote-release.yml in dfinity/icp-cli-network-launcher via an App token scoped to that repo.
• Moves crates/icp-cli/test-network-launcher-version → network-launcher-version (workspace root) and updates all readers (build.rs, the download script, the test module comment, and the bump workflow).

Prerequisite

The pr-automation-bot-public GitHub App must be installed on dfinity/icp-cli-network-launcher with actions: write for the promote dispatch to succeed.

Test plan

Pre-merge:

• cargo build --bin icp and cargo test pass with the moved file.
• YAML lints / Actions parser accepts both new workflows.

Post-merge (the new workflows are only runnable once on main):

• Manually trigger bump-network-launcher with a valid release tag and confirm the PR is opened with the expected branch / title / file content.
• Trigger it with an invalid tag and confirm the verify step fails fast.
• Merge a bump PR and confirm promote-network-launcher fires on main and successfully dispatches promote-release.yml in the launcher repo.

Pull request overview

Adds CI automation around the icp-cli-network-launcher version pin: a manually triggered workflow to bump the pin (with release-tag verification and PR creation via the pr-automation-bot-public App), and an on-push workflow that dispatches promote-release.yml in the launcher repo whenever the pin file changes on main. The pin file is also promoted out of the test crate to the workspace root to reflect its broader role.

Changes:

• Move crates/icp-cli/test-network-launcher-version to network-launcher-version at the workspace root and update build.rs, the test fixture download script, and the test module comment to read from the new location.
• Add bump-network-launcher.yml workflow (manual dispatch) that verifies the release tag, rewrites the pin file, and opens a PR via an App token.
• Add promote-network-launcher.yml workflow that, on push to main modifying the pin file, dispatches promote-release.yml in dfinity/icp-cli-network-launcher with a v-prefixed tag.
