fix(bump-stacks): extract bun edit script to bump.js (heredoc was busted)

Browse Source 
The inline 'cat > /tmp/bump.js <<JS' heredoc died because Gitea Actions
indents the entire run: block, and the closing 'JS' marker for an
unquoted heredoc must sit at column zero. The script never reached
disk and the action exited on a syntax error.

Move the editor into bump.js next to action.yml, reference it via
${{ github.action_path }}.
