spec helpers getting flagged

[stakach]

this seems a little overbearing.
having it correctable breaks things too.

prefixing the file with spec_ solves the issue but that seems redundant given we're in a spec folder.
also seems to flag any file in there, even if it doesn't require "spec" or have any specs in it

maybe we could update this rule to only flag files if they contain actual specs?
i.e. if it's in the spec folder and has describe or it blocks in the file

Hi, first of all the overbearing adjective could be used for any perceived noise, and I don't see any specific relation to this particular rule.

Secondly, the convention is to name the helper as spec_helper.cr, which by default is ignored by SpecFilename rule.

Thirdly, you can either:

• add the files/folders glob(s) as a part of rule's Excluded setting
• add the helper files/folders as a part the rule configuration, see IgnoredDirs and IgnoredFilenames properties:
