feat(cli): add --id parameter to templates init command (#7116)

This PR makes the following changes:

- Adds an --id parameter to coder templates init so that you can non-interactively initialize a specific example template by ID (e.g. folder name)
- Updates develop.sh and lima/coder.yaml to use this parameter to select the docker example template.
