What are the three ways to begin creating a Databricks Asset Bundle, and how do I initialize a bundle using a default template?
1. Use the default bundle template: You can use Databricks CLI version 0.205 or above to run the `bundle init` command, which allows you to choose from a list of available templates.
2. Use a custom bundle template: If you have a custom bundle template, you can use Databricks CLI version 0.205 or above to run the `bundle init` command with the path or URL to the remote bundle template location.
3. Create a bundle manually: You can create a bundle manually by creating a project directory or an empty repository with a third-party Git provider, and then creating one or more bundle configuration files in YAML format.

To initialize a bundle using a default template, follow these steps:

1. Install Databricks CLI version 0.205 or above.
2. Run the `bundle init` command in your terminal or command prompt.
3. Choose a template from the list of available templates.
4. The `bundle init` command will create a new directory with the necessary files and folders for your bundle.

Note: You can view the source for the default bundle templates in the `databricks/cli` and `databricks/mlops-stacks` GitHub public repositories.
