Fix incorrect formatting in all editorconfig files

[bjorn2404]

Description of the Change

Fixes formatting error for crlf line in all repository .editorconfig files. This may have been originally copied over from wordpress-deveop (see link for correct usage). I initially thought of just removing wp-config-sample.php from the files since the purpose isn't 100% clear but instead updated the PR to the correct format.

• Multiple items need to be wrapped with curly braces. Docs on Glob Expressions.
