update golang to 1.22 of fluent-bit base image to fix morestack on g0… (#11904)

**Issue**:

Since version `grafana/fluent-bit-grafana-loki` >= `2.9.2` we could not
run the client due to an error during the startup/forward process where
the container/service crashes and exits with an error message:

`fatal: morestack on g0`

**What this PR does / why we need it**:
A fix was released through the Golang version 1.22.0 and after some
tests (updating the Go version used to the fluent-bit base image), it
seems working fine now.

**Which issue(s) this PR fixes**:
