Summary

./trellis/.vault_pass is required for the trellis dotenv task to run. It'd be great if the dotenv command either:

• Automatically generates ./trellis/.vault_pass if missing during trellis init OR trellis dotenv
• Or throws an error message that informs the user to create one before running the task

Motivation

trellis new creates the ./trellis/.vault_pass but it isn't a commited file, so when a new user clones the repo/project + runs trellis init the vault pass is not created, leading to the error below.

Additional Context

Current error message from trellis dotenv on a project without a .vault_pass file
