refactor(go): remove redundant caching from Go actions

Remove redundant common-cache usage in Go actions since setup-go with
cache:true already provides comprehensive caching.

Changes:
- go-build: Removed duplicate common-cache step (setup-go caches
  ~/go/pkg/mod and ~/.cache/go-build automatically)
- go-lint: Removed redundant ~/.cache/go-build from cache paths
  (kept ~/.cache/golangci-lint as it's linter-specific and not
  covered by setup-go)

Performance improvements:
- Eliminates duplicate caching operations
- Reduces action initialization overhead
- setup-go's native caching is more efficient and maintained

setup-go with cache:true caches:
- ~/go/pkg/mod (Go modules)
- ~/.cache/go-build (Go build cache)
