Tekton Param not being able to expand

Description
What problem/issue/behavior are you having trouble with? What do you expect to see?
We are testing in PAC, this bug may exist in upstream Tekton.

When trying to define Tekton Paramters for ConfigMap/Secret Names, the Param is not being expanded and filling in the underlying value.

Example Snippet:

workspaces:

• name: clone-workspace
  volumeClaimTemplate:
  spec:
  accessModes:
• ReadWriteMany
  resources:
  requests:
  storage: 1Gi
  storageClassName: px-repl2-file

1. Workspace to hold google credentials. The name of the configMap needs to be
2. changed per environment

• name: google-creds
  configMap:
  name: google-creds-$(params.ENVIRONMENT). ### <---- Gets Passed in without Variable being Expanded

1. This workspace will inject secret to help the git-clone task to be able to
2. checkout the private repositories

• name: basic-auth
  secret:
  secretName: "{{ git_auth_secret }}" ### <--- This works

1. This workspace will inject secret for sonarqube analysis

• name: sonar-credentials
  secret:
  secretName: $(tasks.get-params.results.ENVIRONMENT) ### <---- Gets Passed in without Variable being Expanded

What is the business impact? Please also provide timeframe information.
