Cannot update backticked nested field, when it contains / (slash)

### Operating System

MacOS

### Environment (if applicable)

Chrome 131

### Firebase SDK Version

11.0.2

### Firebase SDK Product(s)

Firestore

### Project Tooling

Solid.js

### Detailed Problem Description

Firestore allows to have a map field, whose keys contains slashes, e.g. abc/def/123. You can write a document from js sdk with that kind of fields and keys, however if updating doc with nested field dot notation it throws error: **Paths must not contain '~', '*', '/', '[', or ']'**. The docs says: A quoted field name starts and ends with the backtick character. For example, foo.\`x&y\` refers to the x&y field nested under the foo field.

I know that FieldPath can be used and it works with FieldPaths, but it should work also with backticks.

### Steps and code to reproduce issue

updateDoc(doc(getFirestore(), "doc123"), {["abc.\`def/123/455\`"]: true})
