The glibc 2.35-6 package ships with the C.UTF-8 locale included.
This means there is now a UTF-8 locale available by default and en_US.UTF-8, which requires editing /etc/locale.gen and running locale-gen, is not needed anymore.
A docker container does not need tons of locales in order to do its job,
nor does it need extensive (or any) documentation.
With this change, a bare pacstrapped directory drops from 500MB to 390MB
