Missing local zeroconf replacement directory causes go mod tidy to fail

[ihidchaos]

Hello ,

Thanks a lot for this Matter library—I've been really interested in it and wanted to give it a try! I'm hitting a snag when I try to run go mod tidy though.

The go.mod file has this replace line for github.com/grandcat/zeroconf pointing to ../zeroconf. But that ../zeroconf folder isn't in the repo, so go mod tidy throws this error:

❯ go mod tidy
go: github.com/backkem/matter/pkg/discovery imports
        github.com/grandcat/zeroconf: github.com/grandcat/zeroconf@v1.0.1-0.20230119201135-e4f60f8407b1: replacement directory ../zeroconf does not exist

I figure either the local ../zeroconf directory needs to be added to the repo, or maybe remove the replace if the upstream version works fine now?
