woodpecker: Matrix and `when.evaluate` regression (not evaluating matrix variables)

Component

server

Describe the bug

I used to be able to use the following configuration:

matrix:
  include:
    - TYPE: dev
      MAKE_TARGET: build-dev
      SSH_TARGET: ssh_target_dev
    - TYPE: prod
      MAKE_TARGET: build-prod
      SSH_TARGET: ssh_target

# Run the correct matrix build on the correct branch
when:
  evaluate: |
    CI_PIPELINE_EVENT in ["push", "cron", "deployment", "manual"]
    and ((CI_COMMIT_BRANCH == CI_REPO_DEFAULT_BRANCH) == ("${TYPE}" == "prod"))

To be able to have a workflow which has 95% overlap between prod and dev, but only runs prod on main and dev on other branches.

When updating to 1.0.0, I noticed that this configuration stopped working.

From the logs, I can see that the filter is evaluated once for the whole workflow, and ${TYPE} is empty/not evaluated. I would expect it to evaluate the filter once for each matrix variant instead, as it used to be ~6 months ago.

System Info

Version: 1.0.0
Run on a NixOS host.
