bump golangci-lint to 1.55.0

[jmank88]

Bump and fix new issues:

• File is not goimports-ed with -local X (goimports)

• superfluous-else: if block ends with a continue statement, so drop this else and outdent its block (revive)

• indent-error-flow: if block ends with a return statement, so drop this else and outdent its block (revive)

• dot-imports: should not use dot imports (revive)

Old glitch still remains:

plugins/config_test.go:90: File is not `goimports`-ed with -local github.com/smartcontractkit/chainlink (goimports)
func (m *MockEnvConfig) PrometheusPort() int { return 9090 }
func (m *MockEnvConfig) TracingEnabled() bool { return true }
plugins/loop_registry_test.go:32: File is not `goimports`-ed with -local github.com/smartcontractkit/chainlink (goimports)
func (m *MockCfgTracing) Enabled() bool { return true }

I see that you haven't updated any README files. Would it make sense to do so?
