[Static Analysis worksflow] Retrieve pre-commit version from .pre-commit-config.yaml

[rodoviti]

Can you make pre_commit_tf_tag input optional and then add the "same" logic as you did with terraform_version input?

What i mean is to add a new action, such as get-terraform-version, to retrieve the pre-commit version from .pre-commit-config.yaml file and use it inside static_analysis.yaml workflow if pre_commit_tf_tag input is missing.

What do you think about that?

It looks like it has a default, so it's already optional. Do you mean that the default value may be misaligned from the pre-commit configuration?
