Update timeout for .github/workflows/test-pr.yaml

[team-eng-enablement]

This is an automated pull request to update default timeouts for all jobs in .github/workflows/test-pr.yaml that do not currently contain a default timeout property.

Please review these changes closely to ensure that all jobs have sufficient time to run. If a job needs more time, please add a timeout property to that job to override the organization default.

Additionally, please be attentive to unintended changes to the workflow YAML file, as the parser is not perfect.

Lastly, note that it is up to the reviewer to merge this pull request and delete the PR branch once they are satisfied with the changes.
