fix(storage): add missing type for StringFormat object values

[superguineapig]

Description

This is a TypeScript Type Only change. The type declarations for the storage module were missing the union type that aggregates the string literal values of the StringFormat "enum" object. Without this type, the uploadString function's 3rd parameter expects an Object (corresponding to the StringFormat interface) instead of a string that specifies the format of the uploaded data. This causes a TypeScript compile/check error, but does not otherwise affect the functionality of the function implementation.

This PR adds the appropriate type declaration to satisfy type checking as described in Firebase docs

Test Plan

I don't believe there is a trivial way to write a Jest test for this issue as it involves a type annotation. In my personal code, a @ts-ignore to suppress the error, with subsequent passing of a valid string for the argument resulted in perfectly functional run-time behavior.

The changes in this PR remove the need for the error suppression comment and the dev-time string inference is performed as expected.

It may be noted that there already exists a run-time value assertion to ensure the value for the format argument is one of the expected strings.

See:

react-native-firebase/packages/storage/lib/StorageReference.js

Lines 273 to 279 in 8c631e1

	if (!Object.values(StringFormat).includes(format)) {
	throw new Error(
	`firebase.storage.StorageReference.putString(_, *, _) 'format' provided is invalid, must be one of ${Object.values(
	StringFormat,
	).join(',')}.`,
	);
	}
