fix: update prettier to respect stderr and stdout concurrently

[tractorcow]

In cases where prettier fails to run (see #718) output.stdout can be empty. Generating an annotation with a blank path causes a 422 validation error pushing this check to github.

I have updated the logic to check both stdout and stderr, applying appropriate checks and reporting where available.

For context this is the kind of output.stderr that can be encountered during linting.

[error] src/components/Icon/Icon.stories.tsx: SyntaxError: ',' expected. (32:3)
[error]   30 |     },
[error]   31 |   },
[error] > 32 | } satisfies Meta<typeof Icon>
[error]      |   ^
[error]   33 |
[error]   34 | export default meta
[error]   35 | type Story = StoryObj<typeof Icon>

If I were to parse this instead of output.stdout

Pushed a check to stderr. Below is an example of the check running against my own (failing) codebase. Previously this error would cause a 422 pushing the check to github, and give a false negative (green tick when it should be an error).

Unit tests presented :)

I had trouble even with -no-colors with unit tests locally. Perhaps some limitation of the command line tool?
