[IMPROVMENT] - Change Docs URL constant to the new one

[joaodemari]

Hello Abacate Pay team, I am new here. Trying to contribute with this project.

I noticed that we are using the old Abacate pay docs url in constants.ts file:

export const ABACATE_PAY_DOCS = "https://abacatepay.readme.io/reference";

At the main page, it is poiting to a new documentation url:
https://docs.abacatepay.com/pages/introduction

The old url does not have the documentation about PIXQrCode, it is the v1.0 documentation.

So I think we need to change it.

Thank you for your attention.

Infelizmente o SDK da Abacate ainda continua com esse erro bobo. Fiz um PR que visa usar Bun ao invés de Node, e ele já corrige esse erro bobo (#104 )
