package/rtl8723bu: update upstream

Benetti Engineering just took over Larry Finger(lwfinger)'s repository
rtl8723bu since Larry unfortunately passed away[0](RIP) and there are
pending PRs that will never be checked as stated here[1]. So basically move
github user to benetti-engineering-sas and update version with latest that
fixes build failure with Linux version 6.15. And of course let's update
package's URL due to the moving.
