Support line breaks in inline scripts

[myugan]

I'm trying to use the following code with line continuation:

apt install -y udev \
  systemd-sysv 

However, the build process doesn't handle the line continuation properly and fails to continue with the next command. Currently, this only works when written as a single line:

apt install -y udev systemd-sysv

It would be helpful to add support for line breaks/continuation characters (\) in script_inline blocks to improve code readability, especially for longer commands with multiple parameters.
