Split shell commands into multiple lines for readability

The project's GitHub Actions workflows and tasks contain complex shell command lines.

With the use of the line continuation operator, these commands can be split into multiple code lines. This improves
readability by providing a visualization of the command structure and avoiding excessive line lengths. It also improves
maintainability by making diffs for changes to these commands more clear.

Previously this was done in many commands, but not consistently throughout the project.
