Subject: [PATCH] CI: cancel old e2e-tests on new commits (#6463)

## Problem

Triggered `e2e-tests` job is not cancelled along with other jobs in a PR
if the PR get new commits. We can improve the situation by setting
`concurrency_group` for the remote workflow
(https://github.com/neondatabase/cloud/pull/9622 adds
`concurrency_group` group input to the remote workflow).

Ref https://neondb.slack.com/archives/C059ZC138NR/p1706087124297569

Cloud's part added in https://github.com/neondatabase/cloud/pull/9622

## Summary of changes
- Set `concurrency_group` parameter when triggering `e2e-tests`
- At the beginning of a CI pipeline, trigger Cloud's
`cancel-previous-in-concurrency-group.yml` workflow which cancels
previously triggered e2e-tests
