[Request]: Enforce spaces / line ending in a commit checker

[xiaoxiao921]

Problem

the clang format use tabs, not sure why? I propose https://github.com/YimMenu/YimMenu/blob/master/.clang-format#L67

UseTab: Never

Solution

A simple github action that check for any \t and make the pr not mergeable would be a great thing imo

Reason

incoming pr / whats on the repo always differ, which break git diffs / make them much more annoying to read

Additional context

No response

I thought YimMenu prefers tabs over spaces. https://github.com/YimMenu/YimMenu/blob/master/CONTRIBUTING.md#indents

Why even not allow tabs besides breaking git diffs which should be fixed in the opposite way?

[xiaoxiao921]

the pr is more about an unified way of doing it
