FieldPath only escapes the first \ and '`', resulting in INVALID_ARGUMENT response

[pavadeli]

Environment details

• OS: MacOS
• Node.js version: latest
• npm version: latest
• @google-cloud/firestore version: v7.3.1

Steps to reproduce

1. Try to use a FieldPath with multiple backslashes or backtick, for example:

   query.where(new FieldPath('containing multiple `` or backslashes \\\\'), '==', 0)

2. Run the query, then you get: 3 INVALID_ARGUMENT: Invalid property path ...

This is because of the use of replace in the following line:

nodejs-firestore/dev/src/path.ts

Line 624 in e598b9d

: '`' + str.replace('\\', '\\\\').replace('`', '\\`') + '`';

The replace() method only replaces the first occurence of the given pattern (see MDN for more info).

Thanks for reporting @pavadeli . I'll look into this.
