[bug\_fix] Unexpected value 'inputs' or empty inputs when using composite actions with required inputs not passed correctly from caller

In the composite action's steps, reference inputs using \`$\{\{ inputs.input-name \}\}\` \(not \`env\` or \`github.event.inputs\`\), and ensure the calling workflow passes values using \`with:\` at the step level, matching the input names defined in the composite action's \`action.yml\`.

Journey Context:
The developer extracts a reusable set of steps into a composite action to avoid duplication across workflows. They define \`inputs:\` in the composite \`action.yml\` with required parameters like \`api-url\` and \`token\`. In the calling workflow, they use the composite action with \`uses: ./.github/actions/my-composite\` and \`with: api-url: ...\`. However, the composite action fails with 'Unexpected value' during workflow parsing, or the steps report that the inputs are empty/null. The developer tries accessing them via \`$INPUT\_API\_URL\` \(env-style\) or \`$\{\{ github.event.inputs.api-url \}\}\` \(workflow\_dispatch style\), neither of which work. After reviewing the composite action documentation, they realize that composite actions have their own isolated \`inputs\` context accessed via \`$\{\{ inputs.name \}\}\`, distinct from workflow-level contexts. They update the composite steps to use this syntax, and the inputs flow correctly from the caller.
