Fixes and documentations to pug and parcel

[boray-tw]

Update pug-cli and its Commands

• Reason: pug-cli@1.0.0-alpha6 is dependent of pug@2.0.4 which is of high severity vulnerability reported by npm as shown in the following figure.
  
• Solution:
  • Update pug-cli": "^1.0.0-alpha6 with @anduh/pug-cli": "^1.0.0-alpha8 in package.json. (Reference: pug-cli#86)
  • Update the compiling command of pug from pug to pug3.
• Misc: Add a Windows-version pug-compiling command.

Update parcel, its Commands and Documentations

• Reason:
  1. Parcel@2.4.1 is dependent of an updated version of caniuse-lite. It is reported by parcel as shown in the following figure.
     
  2. Without the setting of --public-url ./ when compiling with parcel, the files cannot be linked to the html file when the html file is viewed locally.
• Solution:
  1. Update parcel and its transformers to 2.5.0.
  2. --public-url ./
• Misc:
  1. Set parcel to be run by npx in the commands defined in package.json.
  2. Add the instructions that commands can be defined in package.json and then be run by npm run <script>.
  3. Add documentations of the 3 options used by parcel: --public-url, --dist-dir and --no-source-maps.
