Multiline mypy errors are cut off after 1 line in ALEDetail window

## Information

**VIM version**

```
NVIM v0.8.0
Build type: Release
```

Operating System: MacOSX 11.5.2

## What went wrong

Multiline errors reported by `mypy` are cut off after 1 line in the `ALEDetail` preview window. For example, for a file containing
```python
def foo(x: list[str]) -> str:
return x[0]

foo((1, 2))
```
If `mypy` linter is enabled (with the `--pretty` option set to `true`) then the `ALEDetail` preview looks like this:

The full output is visible in `ALEInfo`
```
<<>>
multiline.py:4:5: error: Argument 1 to "foo" has incompatible type
"Tuple[int, int]"; expected "List[str]" [arg-type]
foo((1, 2))
^~~~~~
Found 1 error in 1 file (checked 1 source file)
```
Note that if the `pyright` linter is enabled instead, then the full multiline output is visible in `ALEDetail`

## Reproducing the bug
