Add Trivy config file parameters

[bdovaz]

• Add config_file_name and cli_config_arg_name
• Change configuration url to a more suitable one
• Change old urls to the current version
• Fix broken banner image url

I have doubts whether to put /v0.35/ or /latest/.

v0.35:

• Difficult to maintain, it is easy to forget to update the version....
• Aim for the version that corresponds to the one in the image.

latest:

• Not to be maintained.
• It always points to the latest version and it doesn't have to be the one in the image.

@bdovaz I don't remember why we did not use latest
If it works with latest (and returns correctly the version number), go with latest , that's the default way for other linters
