Optimise e2e run (#6513)

## Problem
We have finite amount of runners and intermediate results are often
wanted before a PR is ready for merging. Currently all PRs get e2e tests
run and this creates a lot of throwaway e2e results which may or may not
get to start or complete before a new push.

## Summary of changes

1. Skip e2e test when PR is in draft mode
2. Run e2e when PR status changes from draft to ready for review (change
this to having its trigger in below PR and update results of build and
test)
3. Abstract e2e test in a Separate workflow and call it from the main
workflow for the e2e test
5. Add a label, if that label is present run e2e test in draft
(run-e2e-test-in-draft)
6. Auto add a label(approve to ci) so that all the external contributors
PR , e2e run in draft
7. Document the new label changes and the above behaviour

Draft PR  : https://github.com/neondatabase/neon/actions/runs/7729128470
Ready To Review :
https://github.com/neondatabase/neon/actions/runs/7733779916

and https://github.com/neondatabase/neon/actions/runs/7733854028
