Running as file watcher in container with PyCharm truncates file

I've setup a file watcher that run `ruff --fix` and `ruff format` in a docker image. I've run just one of those commands to isolate the issue and have seen it happen when just `ruff --fix` or `ruff format` is running so it's happening with either command run separately

Here's an example of the error output and when I look at the file, several characters from the last few lines have been removed (i.e. the file was truncated):
```
/Users/dlj/projects/myproject/local/format_file.sh myfile.py
error: Failed to parse myfile.py:117:5: Unexpected token 'exc'
Found 1 error (1 fixed, 0 remaining).
error: Failed to format myfile.py: source contains syntax errors: ParseError { error: UnrecognizedToken(Name { name: "exc" }, None), offset: 3254, source_path: "" }

Process finished with exit code 2
```

Here's the scripts that I use as the watcher (which I have setup in the same manner that [`black` recommends](https://black.readthedocs.io/en/stable/integrations/editors.html#as-file-watcher)):
```
#!/usr/bin/env sh

cd "$(dirname "$0")/.." || exit

if ! local/_run_ruff.sh --fix "$@"; then
exit 1
fi
local/_run_ruff.sh format "$@"
exit $?
```

```
#!/usr/bin/env sh

cd "$(dirname "$0")/.." || exit

docker run --rm \
-v "${PWD}":/usr/src/app:z,cached \
-w /usr/src/app \
ruff:0.1.4 \
/usr/local/bin/ruff "$@"
exit $?
```

On a related note, I know there's a [PyCharm plugin](https://github.com/koxudaxi/ruff-pycharm-plugin) but I like running it in a container, because then [CI and every developer machine is automagically kept in sync](https://github.com/astral-sh/ruff/issues/5072#issuecomment-1779227790)

Here's my `ruff.toml`
```
line-length = 120

select = ["C", "I", "U", "W"]
ignore = ["E", "F", "C901", "W191"]

target-version = "py39"

[isort]
combine-as-imports = true

[format]
# Like Black, use double quotes for strings.
quote-style = "double"

# Like Black, indent with spaces, rather than tabs.
indent-style = "space"

# Like Black, automatically detect the appropriate line ending.
line-ending = "auto"
```

Start with local/format_file.sh, local/_run_ruff.sh, and the supplied ruff.toml, then reproduce the PyCharm watcher through the ruff:0.1.4 Docker image using both --fix and format separately. Compare the file contents before and after each run; done means the watcher no longer truncates the final lines while preserving the reported linting and formatting behavior.
