Accidentally pushed changes from other branch into here, I reverted them.

Good catches, I was the one that created the flaws in116d61e. I wish I realized the second argument ofGET_PED_GROUP_INDEX is redundant since even AB's Native DB it doesn't say it has the second argument iirc, not only alloc8or's.

The first call is redundant because <c>GET_PED_GROUP_INDEX</c> already returns <c>-1</c> when the <see cref="Ped"/> is not in any group.

I had to use an inline code or a code block to reveal hidden HTML element tags, but it looks like you can't use all decorative HTML tags if there's any supported ones. Use the Markdown syntax.

Changed the title "refactor(api-v3): refactor Ped.PedGroup" because it doesn't say any of what the commit achieves other than refactoringPedGroup. People have to see the descriptions or the diffs of commits to understand what or why they change if the titles don't say what they achieve.feat: <some feature names> could be justified because people can guess that's pure feature additions, though.

Also enclosed the property name with backticks as usual since GitHub supports highlighting with inline codes in titles of commits, issues, and pull requests. alexguirre did this several times when committing toSollumz, and some people use this feature when committing toRust's codebase.
