Can't change locale for CLR

[Vasiliy Lutsenko]

Everywhere everything changed successfully (installed additional locale), but CLR assemblies continue to work in POSIX.

Corrected Docker image:

RUN apt-get install --reinstall -y locales
# uncomment chosen locale to enable it's generation
RUN sed -i 's/# sr_RS.UTF-8 UTF-8/sr_RS.UTF-8 UTF-8/' /etc/locale.gen
# generate chosen locale
RUN locale-gen sr_RS.UTF-8
# set system-wide locale settings
ENV LANG sr_RS.UTF-8
ENV LANGUAGE sr_RS
ENV LC_ALL sr_RS.UTF-8
# verify modified configuration
RUN dpkg-reconfigure --frontend noninteractive locales
RUN /opt/mssql/bin/mssql-conf set language.lcid 2074
