Possibility of passing in a token to `download-artifact` [feat req]

[fjeldstad]

What would you like to be added?

Mirroring https://github.com/actions/upload-artifact/issues/455, it would be very useful to be able to specify the token used for accessing the artifacts.

Why is this needed?

When a workflow is triggered by Dependabot, for example, access to artifacts is by default blocked. This means that use cases such as Playwright test sharding (where reports are uploaded as artifacts by matrix jobs and merged into a final report in a separate job) is not possible, at least not without modifying cross-organisation default permissions for automatically created github tokens.
