Update update_dep.sh

Based on the experience of performing dependency bumps, some minor
improvements are made to the script to make it conform to our current
dependency bump procedure, listed as follows:
- print out the dependency's version before and after the bump
- check if the dependency is fully indirect
- change the behavior of bumping dependency (doesn't ignore bumping
indirect dependency in the go mod files anymore)
- check if all dependencies across all go mod files have the same pinned
version respectively after bumping a dependency
