fix: Remove minor version from go.mod

What does this MR do and why?

code-navigation pipeline is failing with this error

example: https://gitlab.com/gitlab-org/gitlab-zoekt-indexer/-/jobs/6662050795#L22

go: errors parsing go.mod:
/builds/gitlab-org/gitlab-zoekt-indexer/go.mod:3: invalid go version '1.22.2': must match format 1.23

This removes the minor version from go.mod file, the go docs say it should be X.Y not X.Y.Z format

How to set up and validate locally

N/A - ci should pass
