fix!: turn off preload tag option by default

[kara]

This commit turns off preload tag generation for
Google Fonts by default because:

• generally preconnect tags should be sufficient
• adding preloads as well runs the risk of resource
  contention with more critical resources
• preloads don't take into account font unicode
  ranges, which could be problematic for i18n
