Updated [csharpier](https://github.com/belav/csharpier) from 1.3.0 to
1.4.0.

<details>
<summary>Release notes</summary>

_Sourced from [csharpier's
releases](https://github.com/belav/csharpier/releases)._

## 1.4.0

## Breaking Changes
### Drop support for net8.0 and net9.0
[#​1888](belav/csharpier#1888)
CSharpier and CSharpier.MsBuild now target `net10.0` and `net11.0`.
CSharpier.Core targets `net10.0`, `net11.0` and `netstandard2.0`.

## What's Changed
### Feature: Support for .NET 11 and C# 15
[#​1888](belav/csharpier#1888)
CSharpier now supports the new syntax in C# 15.
```c#
public union Pet(Cat, Dog, Bird);

public closed record GateState;

HashSet<string> set = [with(StringComparer.OrdinalIgnoreCase), "Hello", "HELLO", "hello"];

outer:
for (int row = 0; row < grid.Height; row++)
{
    for (int column = 0; column < grid.Width; column++)
    {
        if (grid[row, column].IsBlocked)
        {
            continue outer;
        }

        if (grid[row, column].IsGoal)
        {
            break outer;
        }
    }
}
```

### Feature: Avoid chopping single trailing lambda
[#​1865](belav/csharpier#1865)
When the last argument is a lambda with a block body, and the arguments
up to and including the `=>` fit on one line, CSharpier now keeps them
on the same line as the method name.
```c#
// input & expected output
logging.AddFile(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "server{0}.log"), o =>
{
    o.MaxRollingFiles = 1;
});

// 1.3.0
logging.AddFile(
    Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "server{0}.log"),
    o =>
    {
        o.MaxRollingFiles = 1;
    }
);
```
 ... (truncated)

## 1.3.11-beta1



## 1.3.6

# 1.3.6
## What's Changed
#### Fix bug where 2nd instance of VSCode was not able to format code
[#​784](belav/csharpier#784)
