Tidy up core admin module list

@@tra.duong in my opinion hiding module is not a good idea . it will leads to confusion .

@tra.duong, thank you for taking an interest in improving the module list page! You are not the first.

There is an existing, long standing issue for this work, 📌 [PP-3] Figure out what to do with the install/uninstall modules page Postponed . It would be better to discuss your ideas in the issue. Take note, that a Usability review was recently completed, with the results in comment #131.

Therefore, I am closing this as a duplicate.

Thanks!
