Remove an undocumented corner case that might cause Super-linter to
consider a configuration value for a configuration file that points to a
non-existing YAML file as valid. Before this change, Super-linter falls
back to a yml (yaml) extension if the configuration value points to a
non-existing file with a yaml (yml) extension. This workaround dates
back to when Super-linter didn't support customizing configuration file
names.
Now, if the configuration file doesn't exist, Super-linter throws a
fatal error so users can fix their configuration instead.
- 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.
