Show an understandable error when getBuildInfo failed

[sapphi-red]

Is your feature request related to a problem? Please describe.

When getBuildInfo throwed an error, it doesn't show any understandable error and continues the build (and the build fails).

build-image/tests/get-build-info.mjs

Line 4 in 3449ee7

const buildInfo = await getBuildInfo({ rootDir, projectDir });

The only error to notice getBuildInfo failed is:

jq: error (at :1): Cannot iterate over null (null)

Describe the solution you'd like

Show the error thrown from getBuildInfo and stop the build.

Describe alternatives you've considered

Make @netlify/build-info resilient to errors.
