Update the CLI docs path

[adamwg]

Description of your changes

The CLI docs are now versioned separately from the rest of the docs, in preparation for the CLI version diverging from core. Update it in our contributing docs and the CI jobs where we validate generated docs changes. Also update the docs template to match the current documentation page.

While we're here, make the dynamically generated help for crossplane xpkg init stable across runs by sorting the template names. This will reduce unnecessary churn when we automate docs updates.

I have:

• Read and followed Crossplane's contribution process.
• Run ./nix.sh flake check to ensure this PR is ready for review.
  - [ ] Added or updated unit tests.
  - [ ] Linked a PR or a docs tracking issue to document this change.
  - [ ] Added backport release-x.y labels to auto-backport this PR.

📝 Walkthrough

Walkthrough

This PR updates documentation paths and ensures deterministic help output. The docs generation path shifts from content/master/cli/ to content/cli/master/ in CI workflows and contributor documentation. The init command's help text is made deterministic by sorting template names before rendering them.

Changes

Documentation and help output improvements

Layer / File(s)	Summary
Documentation path restructuring .github/workflows/ci.yml, CONTRIBUTING.md	CI validate-docs job and contributing guide example updated to generate and reference command reference from docs/content/cli/master/command-reference.md instead of docs/content/master/cli/command-reference.md.
Deterministic help output for templates cmd/crossplane/xpkg/init.go	Init command imports maps and slices utilities; initCmd.Help() now sorts template names and iterates over them in stable order instead of direct map iteration.

Check name	Status	Explanation
Title check	✅ Passed	The title accurately describes the main change: updating CLI documentation paths across contributing docs and CI workflows.

Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Breaking Changes	✅ Passed	Only cmd/crossplane/xpkg/init.go changed: initCmd flags/args (Directory, RunInitScript, RefName, etc.) are intact; change is just deterministic Help() sorting via maps/slices.
Feature Gate Requirement	✅ Passed	PR #99 only updates CI/docs paths and sorts xpkg init help; no changes under apis/** or additions of experimental API/behavior without feature gating.
Description check	✅ Passed	The pull request description clearly outlines the changes: updating CLI docs paths in contributing docs and CI jobs, updating the docs template, and sorting template names for stable help output. It directly aligns with the changeset across all modified files.

205-205: Keep the CLI docs path updates consistent (and make it a bit more robust)

• generate-docs, Vale, and the failure diagnostic all reference ./docs/content/cli/master/command-reference.md consistently, so they’ll stay aligned.
• The checked-out crossplane/docs repo contains content/cli/master/, so os.WriteFile(... ) shouldn’t fail due to a missing parent directory; optional safeguard: add mkdir -p ./docs/content/cli/master before generate-docs.
