Issue number: resolves #28611

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
It's not possible to pass props that are not camelCase to the `IonNav`
component.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- It is now possible to set a props with kebab-case instead of camelCase
(for example, `root-params` instead of `rootParams`)

## Does this introduce a breaking change?

- [ ] Yes
- [X] No

<!-- If this introduces a breaking change, please describe the impact
and migration path for existing applications below. -->


## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->
⚠️ This is my first PR for ionic so I hope I didn't miss important steps
into the process. I also checked on my project that the fix is working
well. Thank you! 🙂
