Add common method getType to ReactionType interface

Not a big fan of making a generated override for an interface method. The getter is generated in the subtypes using Lombok. I'd argue for explicitly implementing the getter in this case to make the inheritance clearer @rubenlagus your opinion?

@Chase22, this change helps to quickly check a type of reaction by using a getter instead of ugly instanceof.
property = "type" => getType()

Lines 16 to 24 in 7d50276

	property = "type"
	)
	@JsonSubTypes({
	@JsonSubTypes.Type(value = ReactionTypeEmoji.class, name = ReactionType.EMOJI_TYPE),
	@JsonSubTypes.Type(value = ReactionTypeCustomEmoji.class, name = ReactionType.CUSTOM_EMOJI_TYPE)
	})
	public interface ReactionType extends Validable, BotApiObject {
	String EMOJI_TYPE = "emoji";
	String CUSTOM_EMOJI_TYPE = "custom_emoji";

Literally the same was done here: property = "status" => getStatus()

	property = "status")
	@JsonSubTypes({
	@JsonSubTypes.Type(value = ChatMemberAdministrator.class, name = "administrator"),
	@JsonSubTypes.Type(value = ChatMemberBanned.class, name = "kicked"),
	@JsonSubTypes.Type(value = ChatMemberLeft.class, name = "left"),
	@JsonSubTypes.Type(value = ChatMemberMember.class, name = "member"),
	@JsonSubTypes.Type(value = ChatMemberOwner.class, name = "creator"),
	@JsonSubTypes.Type(value = ChatMemberRestricted.class, name = "restricted"),
	})
	public interface ChatMember extends BotApiObject {
	String getStatus();
