Docs: when: manual not supported when using trigger in .gitlab-ci.yml

Problem to solve

On the documentation page for multi-project pipelines, when is documented as a supported keyword for a pipeline job, see the limitations section for multi-project pipelines. However, the value manual does not seem to be allowed.

Further details

The when: manual setting isn't allowed as can be seen when linting the following snippet:

test:
  stage: test
  when: manual
  trigger: some/other/repo

The error shown is

Status: syntax is incorrect

Error: jobs:test when should be on_success, on_failure or always

Proposal

Add to the documentation a section about which values are allowed for when: when setting up a multi-project pipeline.
