fix: scroll back golang-lint version from 1.49.0 to 1.47.3

Golang-lint 1.48+(included) uses gofmt based on go 1.9. The result of
Gofmt based on go1.9 is different from Gofmt based on
go1.18([different](golang/go#54789)). As a
result, Golang-lint 1.48+ reports "File is not `gofmt`-ed with `-s` (gofmt)",
although gofmt(1.8 based) says the code is ok.

Scroll back to golang-lint 1.47.3, which uses gofmt based on go 1.8. In
the future, upgrade golang-lint when go version is higher or equal to
1.9.
