firebase_admin_sdk

Why this change is needed:
Prepares non-breaking patch releases for google_cloud_firestore and
firebase_admin_sdk by dropping WIP staging suffixes and updating version
constants after landing stability fixes and custom headers support.

Summary of changes:

• Bump google_cloud_firestore version to 0.5.3 in pubspec and changelog.
• Remove -wip suffix from firebase_admin_sdk to stage release 0.5.4.
• Add recent Storage.delete() idempotency bugfix item to changelog.
• Regenerate version.g.dart constant to match 0.5.4.

• Fixed double-close errors when calling Storage.delete() prior to FirebaseApp.close().
• Fixed Firestore requests not carrying the SDK's usage-tracking headers (X-Firebase-Client, X-Goog-Api-Client).
• Update dependency googleapis_auth: ^2.3.3 to fix auth/insufficient-permission errors with Application Default Credentials that have no quota project set.

• Require google_cloud: '>=0.4.0 <0.6.0'

• Remove dependency on package:equatable.
• Make Query, CollectionReference, DocumentReference, and CollectionGroup mockable.
• Credential.createClient(List<String> scopes) — create an authenticated AuthClient directly from a credential with custom scopes, without needing a FirebaseApp instance.
• AppOptions.additionalScopes— append extra OAuth2 scopes to the SDK-managed HTTP client without providing your ownAuthClient`.
• FirebaseApp.client is now part of the public API.
• Add support for custom claims in ID tokens.

• Reformatted CHANGELOG.md.
• Update dependency meta: ^1.17.0 to allow workspaces with stable Flutter.
• Removed dependency on package:googleapis_beta.

• New release with a new name. See below for historical context.
