Firestore Functions Triggers Breaks

### Related issues

### [REQUIRED] Version info

**node:** 22

**firebase-functions:** "7.2.5", was also tested with 7.2.6-rc0

**firebase-tools:**

**firebase-admin:** 13.10.0

### [REQUIRED] Test case

```
exports.onDocWriteTest = onDocumentWritten({document: "collectionName/{docID}"}, async (event) => {

})

```

If the document end with empty space " ", for example the document name is "Test Document " with a space in the end, the trigger will results in a crash/error.
For any other document that does NOT end with an empty space, the trigger works as usual.

### [REQUIRED] Steps to reproduce

1. Create a trigger function for any type of document/collection
2. Create a document in the collection where the document ID has a space in the end of it, for example `Document ID `
3. The function will crash upon document write/create

### [REQUIRED] Expected behavior

The trigger should work as intended without crashing

### [REQUIRED] Actual behavior

The function trigger crashes with the following error:

```
Error: Resource name '//pubsub.googleapis.com/' is not valid.

It seems the path extraction breaks at fromSlashSeparatedString
