feat: allow --memory in workflow container options (#1079)
First hand experience to implement this feature can be found at https://codeberg.org/forgejo/forgejo/issues/9406. In a nutshell it is a service container in the CI that randomly uses massive amounts of memory (>50GB RSS) but normally less than 100MB.

---

See also the [matching documentation pull request](https://codeberg.org/forgejo/docs/pulls/1539).

---

It is already possible to limit the memory used by all containers in the config file:

```yaml
container:
  options: --memory 200M
```

This limit can be further reduced (but not increased) by the same option in a job:

```yaml
jobs:
  job:
    runs-on: docker
    container:
      image: code.forgejo.org/oci/node:20-bookworm
      options: --memory 200M
    steps:
      - run: echo OK
```

or a service container:

```yaml
job:
  my-job:
    runs-on: docker
    services:
      pgsql:
        image: postgres:15
        options: --memory 1G
```
