Increase font size in xterm

[voltagex]

FROM jlesage/baseimage-gui:alpine-3.18-v4

# Install xterm.
RUN add-pkg xterm font-terminus

# Copy the start script.
COPY startapp.sh /startapp.sh

ENV HOME=/config
RUN mkdir /config && echo "-*-terminus-bold-r-*-*-40-*-*-*-*-*-*-*" > /config/.Xresources
# Set the name of the application.
RUN set-cont-env APP_NAME "Xterm"

This seems to make the font smaller than not trying to set it at all.

Apologies if I've completely misunderstood how this works.
