Add support for specifying (named) Firestore database ID

[ochoalopezalfredo]

This PR adds the ability to specify the Firestore database ID when initializing Typesaurus. This is useful for projects using multiple databases within a single Firebase project or when connecting to a non-default database.

Changes:

Updated TypesaurusCore.Options interface in src/types/core.ts to include the optional database property.

Updated Firestore initialization in admin src/adapter/admin/firebase.mjs and web src/adapter/web/firebase.mjs adapters to pass the database Id to the getFirestore function.

Bumped package version to 10.7.1 in package.json

Updated CHANGELOG.md file

Usage Example:

import { schema } from 'typesaurus'

const db = schema(
  ($) => ({
    users: $.collection<User>()
  }),
  { database: 'my-custom-db-id' }
)
