paw 改名 rapidapi，而且个人和 5 人以下团队免费了

[cssk]

We are also excited to announce that we are making RapidAPI for Mac free for individual users and teams up to 5! For those who have supported & have previously purchased licenses we’re extending to you a credit you can use across RapidAPI equal to your Paw lifetime license price.
