CI: Revert GitHub Actions for Docker, by hash

All CI Builds have been failing since 18 hours ago:
- apache#18571 (comment)
- https://github.com/apache/nuttx/actions/runs/23389990049

> _The action docker/login-action@v4 is not allowed in apache/nuttx because all actions must be from a repository owned by your enterprise, created by GitHub, or match one of the patterns: 1Password/load-secrets-action@13f58ee, 1Password/load-secrets-action@8d0d610, 1Password/load-secrets-action@dafbe7c, AdoptOpenJDK/install-jdk@*, BobAnkh/auto-generate-changelog@*, DavidAnson/markdownlint-cli2-action@07035fd, DavidAnson/markdownlint-cli2-action@30a0e04, EnricoMi/publish-unit-test-result-action@*, JamesIves/github-pages-deploy-action@4a3abc7, JamesIves/github-pages-deploy-action@d92aa23, Jimver/cuda-toolkit@6008063, Jimver/cuda-toolkit@b6fc3a9, JustinBeckwith/linkinator-action@af984b9f30f63e796..._

That's because ASF Infrastructure Team has mandated that we use the Hash Versions of GitHub Actions for Docker, stated below:
- https://github.com/apache/infrastructure-actions/blob/main/actions.yml
- Which generates: https://github.com/apache/infrastructure-actions/blob/main/approved_patterns.yml
- Due to: apache/infrastructure-actions#547

```yaml
docker/build-push-action:
  10e90e3645eae34f1e60eeb005ba3a3d33f178e8:
    tag: v6.19.2
docker/login-action:
  c94ce9fb468520275223c153574b00df6fe4bcc9:
    tag: v3.7.0
docker/metadata-action:
  c299e40c65443455700f0fdfc63efafe5b349051:
    tag: v5.10.0
docker/setup-buildx-action:
  8d2750c68a42422c14e847fe6c8ac0403b4cbd6f:
    tag: v3.12.0
```

This PR reverts our GitHub Actions for Docker to the hash versions stated above.
