ci: remove git plugin from release process

[jboix]

Description

Removed the @semantic-release/git plugin to avoid making automated commits during the release process. This change simplifies the release flow by only creating a tag without pushing commits to the repository, following the recommendation from semantic release. This also removes the need for handling branch protection rules and bypassing pre-commit hooks during automated commits.

See Making commits during the release process adds significant complexity

Changes Made

• Set the version to dev during development.
• Removed CHANGELOG.md from the repository (the list of changes is available through the release notes).
