fix: install go for static analysis

[gsanchezgavier]

golangci-lint is failing with:

level=error msg="Running error: context loading failed: failed to load packages: failed to load with go/packages: err: exit status 1: stderr: go: errors parsing go.mod:\n/home/runner/work/nri-apache/nri-apache/go.mod:3: invalid go version '1.21.6': must match format 1.23\n"

when loading some of the linters we have configured due to outdated go version in the runner.
Seems to be related with this golang/go#61888
