fix(ci): missing autolabeler permissions

[jvanz]

Description

Adds the missing permissions to allow autolabeler to add labels in the pull requests.

[Copilot]

Pull request overview

This PR updates the GitHub Actions autolabeler workflow to grant write permissions needed for applying labels to pull requests.

Changes:

• Add pull-requests: write to workflow-level permissions in the autolabeler workflow.

[Copilot]

The job already sets permissions, which (per GitHub Actions semantics) overrides the workflow-level permissions. As written, the autolabeler job will only have pull-requests: write and will not inherit contents: read, and adding pull-requests: write at the workflow level will not change the token permissions inside the job. Consider either removing the job-level permissions block (so the job inherits contents: read + pull-requests: write), or explicitly including both permissions at the job level.
