## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->
The Angular implementation of `ion-tabs` does not support conditional
binding the `slot` property on `ion-tab-bar` or assigning a variable as
the slot.
For example, this usage is invalid:
```html
<ion-tabs>
<ion-tab-bar [slot]="slot"></ion-tab-bar>
</ion-tabs>
```
This occurs because `ng-content` only supports static content
projection. It is not intended for scenarios where the content can be
relocated or conditionally rendered.
An example of static content projection would be:
```html
<ion-tabs>
<ion-tab-bar slot="top"></ion-tab-bar>
</ion-tabs>
```
## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
- `ion-tabs` supports conditional slot bindings or a slot that is bound
to a variable in Angular.
The revised implementation relocates the tab bar in the `ion-tabs`
template, based on it's current slot attribute. The implementation
checks the tab bar slot whenever the content changes.

BREAKING CHANGE:
Angular v14 is now required to use `@ionic/angular` and `@ionic/angular-server`. Upgrade your project to Angular v14 by following the [Angular v14 update guide](https://update.angular.io/?l=3&v=13.0-14.0).
The dev-preview `environmentInjector` property has been removed from `ion-tabs` and `ion-router-outlet`. Standalone component routing is now available without additional custom configuration. Remove the `environmentInjector` property from your `ion-tabs` and `ion-router-outlet` components.
