Generated Docker Compose file should use `compose.yaml` instead of `docker-compose.yml`

[9las]

Description:
When creating a new Svelte project using the sv CLI and choosing to include Docker support, the generated file is named docker-compose.yml.

npx sv create my-app
# then select the Docker option

However, according to Docker’s current recommendations, the preferred filename is compose.yaml.

Reference:
Docker documentation

Why this matters:

• Docker Compose V2 supports compose.yaml as the standard name.
• Aligning with the official convention improves clarity and follows modern best practices.
• It also ensures consistency with other tools and official Docker examples.

Suggested fix:
Rename the generated file to compose.yaml in the project scaffolding template when the Docker option is selected.
