fix: --stdin flag

[brianmcgee]

This was incorrectly ported from Rust to Go.

When --stdin is provided, treefmt will copy stdin into a temporary file, using the first path argument as the filename. This allows the user to control which formatters will match this temp file based on their treefmt config.

After the formatters have been applied, the contents of this temporary file are then printed to stdout and the temp file is removed.

Closes #https://github.com/numtide/treefmt/issues/310
