- Remove the SKIP_FLAG variable and check for the length of the arrays
of files to lint directly.
- Remove the LIST_FILES variable, and use the FILE_ARRAY variable
directly.
- Remove the corner case for RENOVATE because renovate-config-validator
supports passing the path to the file to lint using an argument as the
default case does.
- Remove the corner case for ANSIBLE not having 'bad' tests because it
has them now.
- Set TF_DATA_DIR to avoid any modification to any existing Terraform
data directory that users might have in their workspace.
- Aggregate GO_MODULES and ANSIBLE corner cases because they are the
same.
- Remove the corner case for ANSIBLE to add a trailing slash to
TEST_CASE_FOLDER (similar reason as the previous point about ANSIBLE
corner case).
- Simplify log messages by removing color markers because they are
already handled in log.sh.
- Simplify linterVersions by removing redundant checks and functions.
- Avoid printing debug logs in the versions file.
