[Bug]: "Success/failure" behavior is not consistent for file reading and editing

[neubig]

Is there an existing issue for the same bug?

• I have checked the existing issues.

Describe the bug and reproduction steps

In "ran a python command" and "ran a bash command", we have success/failure indicators about whether the command worked well, in the form of green checks or red xs when the command worked or didn't work.

However, when using tools for file reading/editing, currently we get results that are not consistent. If it succeeds we get "Read the contents of a file" or "edited the contents of a file" with no success indicator, and if it fails we get "Ran a python command" with no success indicator.

The expected behavior is:

• Success: "Read the contents of a file" or "Edited the contents of a file" with a success indicator
• Failure: "Read the contents of a file" or "Edited the contents of a file" with a failure indicator

We should:

1. Write tests demonstrating the desired behavior
2. Run these new tests by following the standard workflow in fe-unit-tests.yml to make sure that they fail (demonstrating that the current behavior is undesired)
3. Fix the behavior and make sure that the tests pass
