Fix issues with release workflow

[AlvaroRausell]

Workflow improvements:

• Added workflow_dispatch inputs to allow specifying the release version when manually triggering the workflow.
• Explicitly set contents: write permissions to enable the workflow to push changes to the repository.

Environment setup:

• Added steps to set up Node.js (version 20) and install the devcontainers CLI to support build and release tasks.

Automation and reliability enhancements:

• Configured git user details (user.email and user.name) for automated commits, ensuring proper attribution and avoiding commit errors.
• Moved the branch checkout step to after git configuration and consolidated it with the commit and push steps for improved workflow reliability.
