docs(pipelines): specify how to reference an array parameter

[rguichard]

Changes

This is a small enhancement of the documentation. It gives information about how to reference an array parameter with the syntax ["$(params.parameterName[*])"] (thx @afrittoli ). Which is kind of obvious for an array, but the documentation wasn't clear about it.

Hi @rguichard. Thanks for your PR.

I'm waiting for a tektoncd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
