main

Sync major-9.0 with main after v8.8.3 release.

…k per outlet (#31055)

Issue number: resolves internal

---------

## What is the current behavior?
The swipe-to-go-back gesture on ion-router-outlet is controlled
differently across frameworks:

- React and Vue check the `swipeBackEnabled` config option on every
swipe attempt in their framework wrappers (`StackManager.canStart()` and
`IonRouterOutlet.canStart()`)
- Angular reads the config once at mount and controls the gesture
through its directive's `swipeGesture` setter
- There is no public, per-outlet property to enable or disable the
gesture. The only mechanism is the global `swipeBackEnabled` config
option

## What is the new behavior?
`ion-router-outlet` now exposes a public `swipeGesture` property in core
that controls the swipe-to-go-back gesture per outlet instance. It
defaults to true in "ios" mode and false in "md" mode, matching existing
behavior.

- The `swipeBackEnabled` config is read once when the outlet mounts (as
the default for `swipeGesture`) rather than checked on every swipe
attempt
- The config check has been removed from React's StackManager and Vue's
IonRouterOutlet -- core now owns this state
- Angular's directive forwards the value to the core component's
`swipeGesture` property for consistency
- Apps can disable the gesture on a specific outlet: `<IonRouterOutlet
swipeGesture={false} />`
- Apps that set `swipeBackEnabled` once at startup require no changes

## Does this introduce a breaking change?

- [X] Yes
- [ ] No

## Other information

I tried to align the updates to the BREAKING.md documents with the RR6
PR's changes to it to prevent issues from merging as much as possible

## What is the current behavior?
Ionic Framework uses React 17 and Stencil react-output-target 0.5.3.

## What is the new behavior?
Updated to React 18 and Stencil react-output-target 1.5.0.

- Types updated for compatibility with type changes in React 18.
- `@testing-library/react-hooks` was moved to `@testing-library/react`
so this dependency has been removed.
- `reflect: true` added to `value` prop on ion-radio. Props without
reflection enabled are not rendered in HTML with updated
react-output-target. Issue:
stenciljs/output-targets#476

BREAKING CHANGE:

Drops support for React 17. Applications will need to update to React 18
to be officially supported by Ionic Framework.
