feat: automate deprecated lint rules

[matiasleyba]

Status

READY

Description

• Updated bump_versionscript to also bump the version in pubspec.yaml.
• Unified the logic for fetching linter rules into a single allLinterRules function that uses one endpoint instead of two.
• Created a shared.dart file to consolidate reusable URLs and tags.
• Centralized the logic for updating the excluded rules table in README within a Readme class function.
• Added a script to remove deprecated rules based on the official Dart linter rules (more details on the docs).
• Added a CI workflow to run the analyze script daily and create a PR in case rules are deprecated, example PR and workflow logs.

These changes are part of the changes to implement a better mechanism to automatically detect deprecated lint rules in the VGA #120
