Migrates the Prysm dependency from OffchainLabs/prysm/vX to OffchainLabs/prysm/vY across the entire codebase.

File Modifications

• Replaces import paths in all *.bazel, *.go, *.proto files

File Updates

• Manually updates references in go.mod, .deepsource.toml, hack/update-mockgen.sh, and hack/update-go-pbs.sh

Command Updates

• Regenerates Bazel deps:
  bazel run //:gazelle -- update-repos -from_file=go.mod -to_macro=deps.bzl%prysm_deps -prune=true
• Cleans and fetches Go deps:
  go mod tidy && go get ./...
• Regenerates protobufs:
  ./hack/update-go-pbs.sh
• Cleans bazel files:
  bazel clean --expunge --async
• Regenerates ssz files:
  ./hack/update-go-ssz.sh
• Verifies builds:
  go build ./... && bazel build //cmd/beacon-chain //cmd/validator

The script searches the entire directory tree including potentially large directories like node_modules, .git, or build artifacts. Consider excluding common directories that shouldn't contain Prysm imports, e.g., find . -type f -name \"*.${ext}\" ! -path \"*/node_modules/*\" ! -path \"*/.git/*\" ! -path \"*/bazel-*/*\" -print0.
