Use multiline input parameters instead of JSON input

The `gradle-home-cache-includes` and `gradle-home-cache-excludes` parameters were initially implemented
as JSON string inputs. This makes these inputs non-idiomatic and easier to get wrong.

This change converts them to multi-line input parameters.

Fixes #106
