installation: version check for other tools

[hyangah]

Currently only gopls is doing the version check by querying proxy.golang.org.
We can apply the same approach to other tools.

We need to ensure important tools are installed in modules mode.
Some tools have version commands (e.g. gopls). Otherwise, utilize go version -m command.
