build: Update 'svgo' to latest v3.2.0 and re-minify SVGs

The latest update of 'svgo' dependency includes three optimizations on
converting path commands, which
- improves closing paths and how we determine if to use absolute or
  relative commands.
- round arc or convert to lines based on the geometric sagitta
- convert cubic Bézier curves to quadratic Bézier curves where possible
Also unifiying npm command to qua standard notation `minify:svg`.
