Add test coverage for Web IDE commit error message
Description
Identified in gitlab#455435 (comment 1877463210)
We should add integration or feature spec coverage that the error message for failed commits in the Web IDE is accurate and not generic. This has regressed a few times.
Implementation plan
- This could be a QA spec or Feature spec.
- Ideally this is a feature spec, but these specs are known to be slow and so we want to be aware of the cost.
- Really ideally we'd do this in an integration spec but we don't have this in the Web IDE project
