Allow splitting archives into multiple lines about install-qt-action HOT 1 CLOSED

I suspect you can achieve this already using the following YAML syntax:

archives: >-
  icu
  qtbase
  qtconnectivity

Which is exactly equivalent to:

archives: icu qtbase qtconnectivity

This should work because:

1. the > on the archives: >- line, enables YAML's "folded" block style, so the new-lines are replaced with spaces; and
2. the - at the end of the archives: >- line, enables YAML's "strip" block chomping, which means that the final new-line character is removed too.

So both versions above should result in the same string value: icu qtbase qtconnectivity.

You can have a play with the interactive demo at yaml-multiline.info to see how these multi-line YAML options work.

Cheers.
