This makes the component include path consistent on 16.3/16.5+.

They changed the template structure from:

```
├── template.yml
├── README.md
├── .gitlab-ci.yml
├── unit/
│   └── template.yml
└── integration/
    └── template.yml
```

To:

```
├── README.md
├── .gitlab-ci.yml
└── templates/
    └── all-scans.yml
    └── secret-detection.yml
```

Unfortunately, symlinks are *not* supported so until we can drop support
for 16.3, we'll have to copy over changes.

BREAKING CHANGE: The component must be included via the `bazelisk` name.

The nameless include in `1.0.0-beta.1` is no longer supported.

```
include:
  - component: "${CI_SERVER_HOST}/ci/component/bazelisk@1.0.0-beta.1"
```

Add the `/bazelisk` named CI component:

```
include:
  - component: "${CI_SERVER_HOST}/ci/component/bazelisk/bazelisk@1.0.0-beta.2"
```

This is due to GitLab CI components being stabilised and the nameless component
support being removed.

As of gitlab 16.5 the component dir
structure has changed. Updates the name of
component to match the updated docs.

Move off the beta version.

Pin to 7.0.0rc3 due to upstream regression
in 7.0.0rc4 onwards.

Allows the job to start straight away allowing maximum CI throughput.

Dependencies will need to be added with the `needs`[1] keyword.

This can be useful when setting up shared persistent caches.

We need to sort out a mirroring service for the `.deb`.

We can put them into the GitLab Package Registry.

_Eventually_, we want to be able to drive `semantic-release` from Bazel.

However, that requires hermetic resolution of `git` and `ssh` which is a
challenge that we do not have time for at this time.

`.bazelisk-script` implies everything must be a script reference.

We may want to include other references in the future.

Fragment is better nomenclature here.

BREAKING CHANGE: `.bazelisk-script` is now `.bazelisk-fragment`

Update any `!reference[.bazelisk-script, ...]` to `!reference[.bazelisk-fragment, ...]`

Builds a `bazelisk` image for multiple architectures using `rules_oci`.

Provides a `template.yml` GitLab CI component.
