php-fpm_exporter - fix ftbfs after upgrade to go 1.23 (#27332)

When go moved to 1.23 the result of 'go mod tidy' is different than it
was with 1.22, and the result was an error in go bump like:

> running step "Bump go deps to a certain version"
> Running go mod tidy with go version '1.23.0' ...
> Error: Failed to running update.
> Error: package google.golang.org/protobuf with
>       version 'v1.33.0' is already at version v1.34.2

The 'go mod tidy' updates google.golang.org/protobuf to sufficient
version.
