collection() missing type arguments

There are no exported functions for the collection function that allow a type to be specified. I see reference to collection() in the docs and in the upgrade information (screenshot below) but it isn't working in my project. If I try to add a type to get a typed collection reference, I get the error: Expected 0 type arguments, but got 1.

### Version info

**Angular:** 13.0.3

**Firebase:** 9.0.0

**AngularFire:** 7.2

**Other (e.g. Ionic/Cordova, Node, browser, operating system):** MacOs Montery

### How to reproduce these conditions

**Steps to set up and reproduce**

Attempt to create a collection reference with a custom type

**Sample data and security rules**

The data isn't important.

### Debug output

Error in VS Code:

AngularFire Upgrade Docs:

### Expected behavior

There should be a version of the collection function that takes a type. There are version of other functions that take a type and even expect a typed CollectionReference.

### Actual behavior

No function exists that takes a type.

首先定位导出的 collection() 入口点，并将其与升级文档中引用的其他类型化函数进行比较。使用 issue 中列出的版本，通过 collection() 重现 TypeScript 错误，然后验证自定义类型能够被接受，并且生成的 collection 引用具有类型。
