What
---
1. Add a new job for [`jsonnet-lint`](https://jsonnet.org/learning/tools.html#linter) to lint all jsonnet files
1. Add pre-commit for [`jsonnet-lint`](https://jsonnet.org/learning/tools.html#linter)

Why
---
A human shouldn't be catching problems like
https://ops.gitlab.net/gitlab-com/gl-infra/cells/topology-service-deployer/-/merge_requests/80#note_405253
for unused variables.

At the moment the linter just looks for unused variables but more rules
can be added in the future.

Testing
---

Checking that the image does have `jsonnet-lint` binary installed:
```
$ docker run -it --entrypoint=/bin/sh registry.gitlab.com/gitlab-com/gl-infra/common-ci-tasks-images/go-jsonnet:0.21.0
/ # which jsonnet-lint
/usr/bin/jsonnet-lint
```
