Add Slider to CreateProfileScreen and use for birthExperience

[BekahHW]

Issue
The form is currently incomplete. birthExperience needs a rating input

Describe the solution you'd like

• Add ReactNative slider: yarn add @react-native-community/slider
  -for Ref: https://github.com/react-native-community/react-native-slider

For birthExperience, add in a Component the text: Rate your birth experience (0- traumatic and 10-joyful)
For the slider, the example in the docs will work but change the maximum value to 10

To test
With the app running, click the profile button in the bottom right. This will take you to the CreateProfileScreen, where you should see all your changes.
