`TypeError: Cannot read properties of undefined (reading '1')` in `solc.js` when passing the input for `--standard-json` via stdin

I tried running
`solcjs --standard-json`

and the following output was produced:

> node:fs:208
let mode = stats[1];
^
TypeError: Cannot read properties of undefined (reading '1')

The "^" isn't correctly placed in the above text; it was just below "[" in "let mode = stats[1];"

What's wrong here? `solcjs --abi` and `solcjs --bin` work perfectly well.

Start at the solcjs entry point around line 128, where the stack trace shows readFileSync failing when --standard-json receives input through stdin. Reproduce the command with JSON piped to solcjs --standard-json and determine the expected stdin path; done means that invocation no longer raises the TypeError.
