⚠️ Please do not merge this until we have 2-3 approvals ⚠️

Steps taken:

1.)
In Goland, search for all files with file mask *.bazel and change github.com/prysmaticlabs/prysm/v3 to github.com/prysmaticlabs/prysm/v4

2.)
Do the same for *.go and *.proto files

3.)
Do the same for update-mockgen.sh

4.)
Do the same for hack/update-go-pbs.sh

5.)
Update go.mod module module github.com/prysmaticlabs/prysm/v3 to v4

6.)
Update .deepsource.toml import_paths = ["github.com/prysmaticlabs/prysm/v3"] to v4

7.)
Our grpc gateway, which is a fork we maintain here was hardcoding v3 paths in a template generator. It was updated in a commit here: prysmaticlabs/grpc-gateway#11

Update go.mod and go.sum

go get github.com/prysmaticlabs/grpc-gateway/v2@09284ba20446ebc03dd4cbd5a0c860259b8e5984

Use v2.3.1-0.20230315201114-09284ba20446 in go.mod

8.)
Run gazella
bazel run //:gazelle -- update-repos -from_file=go.mod -to_macro=deps.bzl%prysm_deps -prune=true

Did you run ./hack/update-go-ssz.sh?

Did you run ./hack/update-go-ssz.sh?

Missed this. I ran it and updated the steps. Thank you

[prestonvanloon]

Great work! Looks like some build failures though.

[james-prysm]

james-prysm-v4 got similar results with blobs generated file as the extra file.

[prestonvanloon]

Want to fix this too?

[terencechain]

Ah. Nice catch

[potuz]

I ran different changes with sed magic since I don't have goland. I get a different branch than Terence, but the difference seems to be innocuous. Check against the branch potuz-v4-vis please.

[prestonvanloon]

LGTM. I checked @potuz's branch diff too. looks fine, some difference in deps.bzl ordering and potuz's branch needs to run goimports or manually fix imports that were arranged incorrectly for pb.go.
