Build Rust lambda on Windows fails due to invalid name of binaries

When compiling a lambda for Rust using `cdk deploy` on Windows, the following error occurs:

```
bash: line 1: cargo-zigbuild.cmd: command not found
```

The following command is executed right before the error occurs:

```powershell
docker run --rm -u "1000:1000" -v "C:\\...\\lambda\\input-rust:/asset-input:delegated" -v "C:\\...\\cdk.out\\bundling-temp-03bd30f19334cab2ae18b7174c93b37693217b01635a7c8374264b1c777707ce-building:/asset-output:delegated" -w "/asset-input" cdk-17fb3785ac963db9e8320a984ec540bbbdbce8a3addc1c2485e82f5bb0639a94 bash -c "cargo-zigbuild.cmd zigbuild --manifest-path=/asset-input/Cargo.toml --target x86_64-unknown-linux-gnu --release --color always --bin input-rust && powershell -command Move-Item -Path /asset-input/target/x86_64-unknown-linux-gnu/release/input-rust -Destination /asset-output/bootstrap"
```

As can be seen in the output, the command `cargo-zigbuild.cmd` is supposed to be exeucted. After investigating the image, the command `cargo-zigbuild.cmd` is not part of the image. Only the command `cargo-zigbuild` can be found.

The same project compiles on WSL using Ubuntu 22 without any error.

Looking at the source code of aws-lambda-rust, it is hard coded that on Windows platform, that `.cmd` is always appended to the build command, see:

https://github.com/cdklabs/aws-lambda-rust/blob/6c9a60fcd966745e02949515393946029b78dc0e/src/package-manager.ts#L56

Apparently this leads to errors, because the binaries are not installed with .cmd ending but without it (same as on linux).
