chore: reduce concurrent builds (testcontainers#702)

* chore: reduce concurrent builds

It will avoid multiple pushes to have concurrent builds, aborting
running builds in the followins scenarios:
- for PRs, a new commit will abort running builds for the workflow
- for branches, because it will use the SHA commit as discriminator, a new commit won't abort the running builds

* fix: update generator test
