feat: squash commit of krummbar/bruno-run-action

[krummbar]

Description

Contains the code of krummbar/bruno-run-action. Commit history is squashed into a single commit. If preferred I can also preserve the current history.

The current code reflects the features for bru run cli v1.26.2.

Let me know when you want to publish this action. I'll archive my source repo then and add a reference to the new repository.

Remark

Versioning

For future development we'll need to decide how to proceed with versioning of this action. Currently the bru cli version is backed into the Dockerfile 1.x. So it'll use the most recent version of version 1.
I'm not sure what the best approach is. I could imagine introducing version branches that pin to specific bru cli versions and use a version tag v1 that also points to the latest commit.

• branch/v1.20
• branch/v1.26

While the tag v1 always points to the most recent features. A version branch references then the specified version in the Dockerfile.

However this could introduce increased maintenance effort if a patch is required to all those versions.

Alternative approach is to remove the installation step from the Dockerfile and move it to the entrypoint.sh script and use a optional version input argument for the action.
Effectively users would then be able to specify bru cli version when including it in their actions. But all the other action input arguments would need to be replaced with a generic one.
Going down this path effectively makes all the other input arguments obsolete.

This is how the action could look like in workflows

Branch/Version based approach

- name: Run bruno collection
  uses: usebruno/bruno-run-action@v1.26
  with:
    path: path-to-collection
    env: cicd
    output: bru-run-output.json
    output-format: json

Provide version as argument

- name: Run bruno collection
  uses: usebruno/bruno-run-action
  with:
    path: path-to-collection
    version: '1.26'
    args: --env cicd --output bru-run-oputput.json --output-format json

Maybe you have some better ideas how to proceed here. Just wanted to leave my thoughts on that topic.
