Hide deprecated remix template from app init help text (shop/issues-develop#21581)

[isaacroldan]

WHY are these changes introduced?

Fixes shop/issues-develop#21581

shopify app init --template <invalid> still listed remix in its help text and in the validation error, even though the remix template was removed from the interactive picker in favor of React Router. Users running into the error were nudged toward a deprecated option.

WHAT is this pull request doing?

• packages/app/src/cli/prompts/init/init.ts: set templates.remix.visible = false, matching the existing pattern for node and ruby (still accepted via --template for back-compat, but no longer advertised in help text, validation errors, or generated docs).
• Added two unit tests asserting visibleTemplates excludes remix and equals ['reactRouter', 'none'].
• Regenerated the artefacts that make refresh-manifests / refresh-readme / build-dev-docs produce: packages/cli/oclif.manifest.json, packages/create-app/oclif.manifest.json, packages/cli/README.md, docs-shopify.dev/commands/interfaces/app-init.interface.ts, and the two generated_docs_data*.json files.
• Patch changeset for @shopify/app.

How to test your changes?

1. From this branch, run:

   shopify app init --template not_a_real_template
   

2. Expect the validation error to list only reactRouter and none — no remix.
3. Confirm shopify app init --template remix still works (back-compat preserved).

Pull request overview

This PR hides the deprecated remix app template from shopify app init --template help/Docs output while preserving backward compatibility for --template remix.

Changes:

• Mark the remix predefined template as not visible, so it’s omitted from help text and validation messaging.
• Update generated oclif manifests, CLI README command docs, and docs-shopify.dev generated docs to remove remix from the advertised --template aliases.
• Add a small unit test to ensure visibleTemplates excludes remix and only exposes the currently offered aliases.
