prodigenr 0.6.2

Minor changes and CRAN fixes

• Removed Distill from imports and from created report, switching to using Quarto
  instead (e.g. with YAML metadata).
• Removed AppVeyor.
• Rearranged project creation to copy an internal folder (with necessary files)
  into the specified folder on the users computer. This hopefully will make it easier
  to add other templates later on.
• Updated package aims to be clearer and more focused.
• Fixes to CRAN notes about HTML5.
