fix: use a single source of truth for the go version (elastic#15583) (elastic#15606)

go version is defined in two places: go.mod and .go-version
they often get out of sync and it's not clear which is used where.
CI is using the version defined in go.mod which might be outdated compared
to .go-version.

bump go version in go.mod and ensure scripts are using it consistently

remove old jenkins scripts

(cherry picked from commit c24a1cb)
