chore: deprecate leveldb ecosystem

[AlbaHerrerias]

⚠️ This deprecate-leveldb-ecosystem branch is based on node-sqlite-adapter, so the original PR should be merged first. For that reason we are submitting this as a draft.

⚠️ The checks on this PR will not pass until we remove the ones that depend on Node.js 20. Here is the PR that removes them, and should be merged first

Overview

Hello! 👋

We are from the Neighbourhoodie Software, the implementation partner of the STA Bug Resilience Program. This work is part of our agreed 'Milestone 1. Deprecate and Remove LevelDB Subsystem'.

This PR is a continuation of the one that introduces the nodesqlite adapter. Here we deprecate all LevelDB ecosystem dependencies, adapters, etc., which was agreed to be merged in the next+1 major version

Please note that some test were deleted because, as our understanding, these were made for the LevelDB adapters. If this is incorrect, please say so and we will address the requested changes.
