refactor(productcatalogservice): refactor productcatalogservice dockerfile

[tranngoclam]

Changes

• Use golang:1.22-alpine instead of golang:1.22.x-alpine to always get the latest patch version. (i.e: currently golang:1.22-alpine will resolve the go version: 1.22.1 (latest))
• Use mount type=cache and type=bind from buildkit spec (this is also suggested by command docker init) for better performance when running docker build.
• Use go list command to install go tools in tools.go with versions locked in go.mod
