TypeScript: Allow decorators to be used with declare on class fields (#19492 by @​evoactivity)

Extensively used within the Ember ecosystem, decorators with declare on class fields will ignore the babel parser error and allow Prettier to format the code without breaking it.

// Input
export default class ProjectStatusComponent extends Component<ProjectStatusSig> {
  @service declare server: ServerService;
}
// Prettier 3.9.1
// SyntaxError: Decorators can't be used with a declare field. (2:3)
//  1 | export default class ProjectStatusComponent extends Component<ProjectStatusSig> {
//> 2 |   @​service declare server: ServerService;
//    |   ^
//  3 | }
// Prettier 3.9.3
export default class ProjectStatusComponent extends Component<ProjectStatusSig> {
@​service declare server: ServerService;
}
