[Task] Publish application_runner to a public repo

[taorepoara]

What should be done

In order to get the dependencies versions we need to publish them to a public repo just like it's done for query parser: https://github.com/lenra-io/query-parser/blob/beta/.github/workflows/semantic_release.yml

Technical recommandation

Set lenra_common, application_runner and server versions before publishing them in order to get there version with the next code:

$ iex -S mix
iex(1)> Application.spec(:application_runner, :vsn)

The version must be set before the Docker build in order to have the right version in the code.

Ecological concerns

Only publish application_runner if there no need to publish lenra_common and server.

Is this task linked with any other ?

This is needed for the next issues:

• Create an endpoint to get the devtool version devtool#173
• Create an endpoint to get the server version #332
