Hints for kbreakout in main

Hints

• asv-unknown-tag
  :6 - developer
  Found invalid tag. Non-standard tags should be prefixed with `x-`. AppStream also provides the <custom/> tag to add arbitrary custom data to metainfo files. This tag is read by AppStream libraries and may be useful instead of defining new custom toplevel or `x-`-prefixed tags if you just want to add custom data to a metainfo file.
• asv-summary-has-dot-suffix
  :70 - „KBreakOut“ ir KDE spēle, kas atgādina zināmo „Breakout“ arkādes spēli.
  The component summary should not end with a dot (`.`).
