Prometheus: Restore FromAlert header (#55255)
This restores the FromAlert header to prometheus for Grafana managed alert Queries. 

It does this by reverting "Prometheus: Remove middleware for custom headers (#51518)" , but also changing it so it is only the FromAlert header.

This reverts commit 2372501368.

Chore: Upgrade Go to 1.19.1 (#54902)
* WIP

* Set public_suffix to a pre Ruby 2.6 version

* we don't need to install python

* Stretch->Buster

* Bump versions in lib.star

* Manually update linter

Sort of messy, but the .mod-file need to contain all dependencies that
use 1.16+ features, otherwise they're assumed to be compiled with
-lang=go1.16 and cannot access generics et al.

Bingo doesn't seem to understand that, but it's possible to manually
update things to get Bingo happy.

* undo reformatting

* Various lint improvements

* More from the linter

* goimports -w ./pkg/

* Disable gocritic

* Add/modify linter exceptions

* lint + flatten nested list

Go 1.19 doesn't support nested lists, and there wasn't an obvious workaround.
