include interpolation doesn't support dynamic variables

[fatmcgav-depop]

Follow on from #942

We have a use-case where we would like to use "dynamic" variables as part of the path for an included Taskfile.

e.g.

---
version: "3"

vars:
  MODULE_NAME:
    sh: jq -r .module_name cookiecutter.json

includes:
  # Support running tasks defined in the generated template module
  generated:
    taskfile: './cookiecutter-temp/{{ .MODULE_NAME }}'
    dir: './cookiecutter-temp/{{ .MODULE_NAME }}'
    optional: true

Note that #943 added support for "static" variables, this ask is specifically for dynamic variable support.
Also see #942 (comment)

Thanks for creating the issue. Since the current docs only mention using static variables, I'm going to categorise this as an enhancement and we can add something to the docs to explicitly say this is supported once its resolved.

This could also improve the security aspects of #1317:

vars:
  GITHOST_TOKEN:
    sh: security find-generic-password -s "Git host token" -w

includes:
  compose: https://git:{{.GITHOST_TOKEN}}@example.com/shared/taskfiles.git//Tasks.yaml?ref=main

On macOS you can store tokens in the Keychain using the security CLI.
On GNOME-based Linux distributions you can do something similar with secret-tool.
