show-method-in-nav-bar should default to true when use-path-in-nav-bar is on

[pmcelhaney]

When use-path-in-nav-bar is enabled, the request method should be visible by default.

Example from https://rapidocweb.com/examples/nav-item-as-path.html

I needed to add show-method-in-nav-bar to disambiguate the operations.

I'm willing to open a PR if you let me know which solution you prefer.

1. Make the default value for show-method-in-nav-bar equal to the value of use-path-in-nav-bar.
2. Don't change the API but mention in the docs that you probably want to use use-path-in-nav-bar if you have show-method-in-nav-bar enabled. Also change the example link in use-path-in-nav-bar to the the example with buttons for showing the method
3. Something else?

I'm leaning toward the second option because it won't be a breaking change.

Thanks for the suggestion,
I will update the docs and example to make it more clear
