pkg/internal/expression: make `expression` to not depend on `context` instead `Dig`

See merge request !8

workflow: use `aarch_64` to fetch `protoc`

See merge request !12

This allows generic support for digging into object using
`json` compatible syntax. This supports common structures
based on objects, or protobuf values.

pkg/step: read `proto.StepDefinition` directly

See merge request !10

This exposes only `Read/Write/Serialize/Deserialize`
methods to parse step definition from the file.

The `step-runner ci` also consider this as a regular
`step.yml` which is constructed dynamically.

Reuse remote cache

Closes #1

See merge request !7

pkg/step: dry `read.go` to unify how proto is read

Closes #2

See merge request !9

Publish temporary images to `registry.gitlab.com/.../pipelines:$IID`

See merge request !6

Improve interpolation by re-working `Evaluate` and `Expand`

See merge request !3

Make `Expand` to retain type for a simple expansions allowing to deep pass entries

See merge request !5

This avoids polluting main registry repository
with ephemeral tags.

Example:

```yaml
- step: step-name
  inputs:
    features:
      ping:
        color: red
      pong:
        color: blue
```

```yaml
...
---
type: steps
steps:
  - step: step-name-2
    inputs:
      config: ${{ inputs.features.ping }}
```

```yaml
...
---
type: exec
exec:
  command: [echo, "Passed color: ${{inputs.config.color}}"]
```

This makes a few changes:

- Introduces `ExpandString` that is meant to handle simple expressions
  - Error if keys are not to be found
- Reworks the `interpolateString` to track the `${{` and `}}`
  - Generate errors for misaligned `${{`
  - Make `Runner` to pass error messages from interpolation end evaluation
- Make `Expand` to always mutate structure and list
