Apply conventions to existing Actions and Workflows

This commit applies the conventions that we documented on our wiki, see
https://github.com/spring-projects/spring-boot/wiki/GitHub-Actions.

In no particular order this:

* Use consistent single quotes for descriptions
* Order elements in a predictable order. In particular, inputs, outputs,
and environment variables are ordered alphabetically
