## Problem
Azure login fails in `pin-build-tools-image` workflow because the job
doesn't have the required permissions.
```
Error: Please make sure to give write permissions to id-token in the workflow.
Error: Login failed with Error: Error message: Unable to get ACTIONS_ID_TOKEN_REQUEST_URL env variable. Double check if the 'auth-type' is correct. Refer to https://github.com/Azure/login#readme for more information.
```
## Summary of changes
- Add `id-token: write` permission to `pin-build-tools-image`
- Add an input to force image tagging
- Unify pushing to Docker Hub with other registries
- Split the job into two to have less if's
## Problem
We use ubuntu-latest as a default OS for running jobs. It can cause
problems due to instability, so we should use the LTS version of Ubuntu.
## Summary of changes
The image ubuntu-latest was changed with ubuntu-22.04 in workflows.

## Problem
`build-build-tools-image` workflow is designed to be run only in one
example per the whole repository. Currently, the job gets cancelled if a
newer one is scheduled, here's an example:
https://github.com/neondatabase/neon/actions/runs/8419610607
## Summary of changes
- Explicitly set `cancel-in-progress: false` for all jobs that aren't
supposed to be cancelled
## Problem
Currently, after updating `Dockerfile.build-tools` in a PR, it requires
a manual action to make it `pinned`, i.e., the default for everyone. It
also makes all opened PRs use such images (even created in the PR and
without such changes).
This PR overhauls the way we build and use `build-tools` image (and uses
the image from Docker Hub).
## Summary of changes
- The `neondatabase/build-tools` image gets tagged with the latest
commit sha for the `Dockerfile.build-tools` file
- Each PR calculates the tag for `neondatabase/build-tools`, tries to
pull it, and rebuilds the image with such tag if it doesn't exist.
- Use `neondatabase/build-tools` as a default image
- When running on `main` branch — create a `pinned` tag and push it to
ECR
- Use `concurrency` to ensure we don't build `build-tools` image for the
same commit in parallel from different PRs
