chore: remove import hack for protobuf any

[rootulp]

Closes #744

This import hack doesn't seem necessary b/c it doesn't actually modify x/blobstream/types/query.pb.go

Testing

$ rm x/blobstream/types/query.pb.go
$ make proto-gen

and then observe that there is no git diff so no changes to the already checked in x/blobstream/types/query.pb.go and the generated one.

Also proto-gen passes in CI: https://github.com/celestiaorg/celestia-app/actions/runs/6881660922/job/18718509598?pr=2846

I ran the testing process (after removing the replacement command in the bash script); I can also confirm that the import path of the types package points to the cosmos types package i.e.,github.com/cosmos/cosmos-sdk/codec/types. This renders the import hack unnecessary and safe to remove.

it seems like we can remove this as the protobuf is no longer changing, but I'm curious as to what changed that fixed this. Was it the update to gogo proto?

will defer @sweexordious for final approval to be abundantly cautious and for additional context

Weird, tested it and it's not needed anymore 🎉
