Add languages and build_mode to init success status report

[henrymercer]

Fix a typo where we wouldn't pass a config to the init success status report. While we're here, defensively pass config to the other createStatusReportBase calls too.

Merge / deployment checklist

• Confirm this change is backwards compatible with existing workflows.
• Confirm the readme has been updated if necessary.
• Confirm the changelog has been updated if necessary.

Fair enough, we might need those configs one day in the other status reports 😆

Merging in before I kick off a release!
