### Godot version

v4.0.beta.custom_build [d1e5903c6]

### System information

Arch Linux kernel 6.1.7-arch1-1 x86_64 OpenSSH 9.1p1-3

### Issue description

When using SSH remote deploy, if the deploy target has a pre-login message like Arch [/etc/issue](https://man.archlinux.org/man/issue.5) the SSH output is treated as only the first line and the output becomes the pre-login message like in the example below "Welcome to Arch Linux"

```
Creating temporary directory...
Executing: ssh -p 22 -p 22 davi@192.168.1.50 mktemp -d
Exit code: 0, Output: Welcome to Arch Linux
/tmp/tmp.BOugkHj1WF
```
Then, the SCP command is not executed as intended
```
Uploading archive...
Executing: scp -P 22 -P 22 /home/davi/.cache/godot/linuxbsd/tmp_linuxbsd_export.zip davi@192.168.1.50:Welcome to Arch Linux
Uploading scripts...
Executing: scp -P 22 -P 22 /home/davi/.cache/godot/linuxbsd/tmp_linuxbsd_export_start.sh davi@192.168.1.50:Welcome to Arch Linux
Executing: ssh -p 22 -p 22 davi@192.168.1.50 chmod +x "Welcome to Arch Linux/tmp_linuxbsd_export_start.sh"
Exit code: 1, Output: Welcome to Arch Linux
chmod: cannot access 'Welcome': No such file or directory
chmod: cannot access 'to': No such file or directory
chmod: cannot access 'Arch': No such file or directory
chmod: cannot access 'Linux/tmp_linuxbsd_export_start.sh': No such file or directory

Welcome to Arch Linux
chmod: cannot access 'Welcome': No such file or directory
chmod: cannot access 'to': No such file or directory
chmod: cannot access 'Arch': No such file or directory
chmod: cannot access 'Linux/tmp_linuxbsd_export_start.sh': No such file or directory
```

If not fixed that should be at least a documentation note (when it is written) for the user to disable pre-login messages if possible.

### Steps to reproduce

1. Enable a project to deploy with ssh
2. Set a host with pre-login message
3. Try to deploy
4. See the error on the console
