docs(analytics): add analytics type declaration file to fix its absence in the reference API on the docs website

[CatWithNineLives]

Description

• The analytics API wasn't mentioned in the reference docs. Fixed it by generating a type declaration file for analytics so that its documentation can be automatically added to https://rnfirebase.io/reference

• While locally building the docs website, faced the following eslint related error :

This was happening due to a version mismatch between eslint-plugin-react and eslint

eslint-plugin-react v7.32.2 is the last version that supports ESLint 6. Version 7.33.0+ added generator functions that require ESLint 8's JavaScript engine.

- Updated `eslint` to `8.57.0` to support  `eslint-plugin-react` `v7.37.5`
- Updated the prettier and typescript packages to match ESLint 8
- Updated .eslintrc.js with root: `true` to isolate the website from the root `ESLint 9` config (which was interfering)

Release Summary

• Added analytics to the reference API docs
• Fixed eslint issues in the documentation website
