feat(jq): add json convert json tfsec to rdjson

[jplanckeel]

Hello,

exchange in this issue the links to the solutions do not come up, the idea would be to make a json converter from tfsec to rdjson with jq.

This PR install JQ and change tfsec ouput by json, parsing jq to translate to rdjson and change input format for reviewdog

Result :

We do not need to install jq as every Available Environment has jq by default. https://github.com/actions/virtual-environments#available-environments

[jplanckeel]

yes, on entreprise we don't use runner with jq :/ i fix them

[jplanckeel]

is fixed can you re-run pipeline ? :)

[haya14busa]

oh, i see.

It's ok to include installing jq script when it's not available and it support windows/mac.

Hi, this change is breaking the action in cases where there are no tfsec warnings.

Repro steps

1. Find a terraform directory with no tfsec violations, confirm with the following command:

$ tfsec --format=json . | jq .
{
  "results": null
}

2. Run the command added in this PR, using the filter file in this repository:

$ tfsec --format=json . | jq -r -f <your_path>/to-rdjson.jq
jq: error (at <stdin>:3): Cannot iterate over null (null)

I am not a jq expert, but I believe the error is introduced here:

  diagnostics: .results | map({

Cheers!

ETA: better to fix than to complain: #27
