feat: camelCase Angular (kebab-case removal)

BREAKING CHANGE:

Angular is now fully camel case.

Before:

    <p *ng-if="cond">
    <my-cmp [my-prop]="exp">
    <my-cmp (my-event)="action()">
    <my-cmp [(my-prop)]="prop">
    <input #my-input>
    <template ng-for #my-item [ng-for-of]=items #my-index="index">

After

    <p *ngIf="cond">
    <my-cmp [myProp]="exp">
    <my-cmp (myEvent)="action()">
    <my-cmp [(myProp)]="prop">
    <input #myInput>`,
    <template ngFor="#my-item" [ngForOf]=items #myIndex="index">
