fix(ext/node): convert errors from `fs.readFile/fs.readFileSync` to node format (#26632)

Fixes the original issue reported in #26404. storybook runs into other
errors after this PR (the new errors will be fixed in other PRs).

Some code used by a dependency of storybook does a [string comparison on
the error
message](https://github.com/chromaui/chromatic-cli/blob/ce30b2be343cb96a0826390b95ea42befb2be547/node-src/lib/getConfiguration.ts#L88-L92)
thrown here to check for a file not found error.
