This commit introduces two new Makefile targets:
- `sync-to-github`: Synchronizes the local repository to a GitHub remote.
It will add the 'github' remote if it doesn't exist and then push all
branches and tags. The GitHub repository URL is configurable via the
`GITHUB_REPO_URL` variable (e.g., `https://github.com/josedario87/your-repo-name.git`).
- `sync-to-gitea`: Synchronizes the local repository to a Gitea remote.
It will add the 'gitea' remote if it doesn't exist and then push all
branches and tags. The Gitea repository URL is configurable via the
`GITEA_REPO_URL` variable, which uses placeholders for server details
(e.g., `ssh://<GITEA_USER>@<GITEA_HOST>:<GITEA_PORT>/nucleo000/your-repo-name.git`).
Both new targets have been added to `.PHONY` to ensure correct behavior.
The repository name is dynamically determined from the local Git configuration.
