[docs] Apache Casbin Plugins `Want to contribute a new plugin?` button alt text

[gubertoli]

Hi,

Going through the webpage to make a contribution, the alt text in the Apache Casbin Plugin contributors call-to-action button mentions (click to open tableData folder):

https://github.com/casbin/casbin-website-v2/blob/219d05e8c35dcb633c1b90adae45bd1e5e330938/src/pages/ecosystem/_components/ShowcaseHeader.jsx#L10

With the link pointing to:
https://github.com/casbin/casbin-website-v2/blob/219d05e8c35dcb633c1b90adae45bd1e5e330938/src/pages/ecosystem/_components/ShowcaseHeader.jsx#L7

By the wording, must it point to https://github.com/casbin/casbin-website-v2/tree/master/src/tableData or to remove the (click to open tableData folder) excerpt ?
