[.github] disable too many lines check

- we are aware of that some modules are too long but bothering us every time is not very helpful. However, the preset 1000 lines is a relatively small number. (Personally I prefer for better overview more in a single file since then search & replace, comparing code etc. is easier than having 10 files with each 100 lines opened.)
