Interpolate environment variables directly in the manifest.yml syntax (similar to what TaskFile/GH actions does)

[Excoriate]

🌟 Feature Description

It'd be great to interpolate and dynamically replace values (E.g.: commands) in the manifest.yml file based on the already exported environment variables from the host.

🚀 What's the Benefit?

Flexible and easy-to-customize manifest files.

🛠️ Proposed Solution

Use the following syntax:

${{env.MY_ENV}}

It'll look familiar with those users that works extensively with Go templating, GitHub actions, Taskfiles, among other nice/modern tools.
