If the input name has a dash the `${{ .inputs.input-name }}` syntax doesn't work

[RothAndrew]

Environment

Device and OS:
App version: UDS CLI v0.24.0
Kubernetes distro being used:
Other:

Steps to reproduce

1. Make a task with an input that has a dash in its name

Expected result

All 4 types of valid input syntax work:

1. $INPUT_MY_INPUT
2. ${INPUT_MY_INPUT}
3. ${{ index .inputs "my-input" }}
4. ${{ .inputs.my-input }}

Actual Result

Only 1, 2, and 3 work. 4 fails with error of "bad substitution"

Visual Proof (screenshots, videos, text, etc)

Severity/Priority

Additional Context

This is unrelated to the new changes from #184. I checked out v0.5.0 and tested with that version and it exhibited exactly the same behavior.

[Noxsios]

in maru2 inputs now use a function access:

${{ input "foo-bar" }}
vs
${{ .inputs.foo-bar }}

to better support input names that contain - and other special characters
