Send mainPath and configDir on update success/failure

[tmeasday]

Telescoping on https://github.com/chromaui/addon-visual-tests/pull/41

Send the main.js location and configDir up on success/failure so we can incorporate it into the UIs.

To QA:

1. Clear the selected options from main.ts: https://github.com/chromaui/addon-visual-tests/blob/1f7b002a58d160c755bb363e686b62cc64de9c42/.storybook/main.ts#L40

2. Make findConfig error, select a project, check you see generic instructions (no specific main location)

3. Make updateMain error, select a project, check you see instructions that include main.ts

4. Make it all work, select a project, check you see a message that includes main.ts.
