Modal - automate updating from deprecated Modal to new implementation

[thatblindgeye]

Follow up to comments in #808 and breaking change PR patternfly/patternfly-react#10799. This also would rely upon #809 getting in first.

We should provide a codemod that helps consumers automate an upgrade from the deprecated Modal (which will have had its import path updated to the deprecated directory as part of another codemod) to the current composable implementation. This would include:

• updating the import path back to non-deprecated
• importing other subcomponents
• grabbing certain props from Modal and creating a new structure based on those props
• removing props from Modal

Required actions:

1. Build codemod
2. Build test
3. Update readme with description & example
