As per 'Documentation/CodingGuidelines', we try to keep to at most 80 characters per line. However, there are often certain cases where we extend this for the sake of readability.

Add a maximum limit of 120 characters to the '.editorconfig'. This means that if an individual line exceeds 120 characters, the editor will wrap that line. This provides a lot wiggle room over the recommended 80 character limit.

Contrary to settings within '.clang-format' which are used for statically formatting source code, the '.editorconfig' rules are hints to the editor. These are not enforced by CI and are guidelines for editors to follow. As such, the 'max_line_length' used here is only supported in a set of editors [1].
