1.4.4 broken on arm32

## Environment

* Operating system (including version):
* Raspbian 11 (Bullseye) on Pi3 (arm)
* mkcert version (from `mkcert -version`):
* 1.4.4
* Server (where the certificate is loaded):
* Client (e.g. browser, CLI tool, or script):

## What you did
```
apt install wget curl libnss3-tools
wget https://github.com/FiloSottile/mkcert/releases/download/v1.4.4/mkcert-v1.4.4-linux-arm
chmod +x mkcert-v1.4.4-linux-arm
./mkcert-v1.4.4-linux-arm
```

## What went wrong
```
An error occurred trying to start process '/usr/bin/mkcert' with working directory '/home/freddie'. Exec format error
```

Note that 1.4.3 works fine:
```
> mkcert --version
v1.4.3
> mkcert -install
Created a new local CA 💥
The local CA is now installed in the system trust store! ⚡️
