Change the default inheritance to true

The plugin document says "inherited" is true by default:

"The plugin analyzes the latest patch set by looking at each file
directory and building an OWNERS hierarchy. It stops once it finds an
OWNERS file that has “inherited” set to false (by default it’s true.)"

This change changes the default value to true to match the document.
