Handle non-strings in createActionParametersFromRequest

[hparra]

Description

Fix unhandled exception when createActionParametersFromRequest receives actionInputs values that are not strings, e.g.

# ...
      actions:
        getStageAdobeCom:
          function: ../../.build/dx-excshell-1/packages/health/actions/getStageAdobeCom.js
          runtime: nodejs:18
          web: "yes"
          annotations:
            require-adobe-auth: false
            final: true
          inputs:
            <<: [*baseInputs, *ADOBE_KEYS]
            TIMEOUT_PER_CHECK: 10000
            urls:
              - https://blog.stage.adobe.com # blog
              - https://business.stage.adobe.com # bacom
              - https://business.stage.adobe.com/blog/ # bacom-blog

              - https://www.stage.adobe.com # homepage

This is a naive fix. Hypothetically we should handle interpolation of strings within array or object but it's Friday evening and my own use-case works now. I didn't even know interpolation like this was thing.
