Description:

Currently, the tailcall init command is not optimized for reinitializing a Tailcall project after updating the Tailcall version. This process can be made more seamless with the following enhancements:

1. Auto-detection of Configuration Format:

   • When reinitializing a project, the command should automatically detect the configuration format (GraphQL/YAML) based on existing files in the folder (e.g., .tailcallrc.graphql or .tailcallrc.yaml).
   • Only prompt the user to choose a format if no configuration file is detected.

   Example Improvement:
   Instead of showing:
   
   Automatically infer the format from the existing file.

2. Skip Confirmation for Overwriting .tailcallrc:

   • Overwriting the .tailcallrc file should not require user confirmation, as it is mandatory for IDEs to understand the Tailcall configuration.

   Current Behavior:
   
   Proposed Change: Automatically overwrite the file without prompting.

3. Skip Overwriting main.graphql:

   • Reinitializing should not overwrite main.graphql

   Current Behavior:

   main.graphql already exists. Overwrite? (y/n)  

   Proposed Change: don't overwrite main.graphql.

These changes will improve the developer experience by reducing unnecessary steps and making the tailcall init command more intuitive during reinitialization.

Steps to Reproduce Current Behavior:

1. Run tailcall init in an existing Tailcall project directory.
2. Observe the prompts for configuration format and confirmation to overwrite files.
