fix(rstudio timeout): increase timeout

[Jose-Matsuda]

Hopefully addresses https://jirab.statcan.ca/browse/BTIS-1021

[Jose-Matsuda]

If this doesn't work, consider just adding (changing) the auth-timeout-minutes to be a big number. Though from this documentation it should have been fine with

    echo "auth-stay-signed-in-days=7" >> /etc/rstudio/rserver.conf && \
    echo "auth-timeout-minutes=0" >> /etc/rstudio/rserver.conf && \

is also noted here

As for

    echo "session-timeout-minutes=10080" >> /etc/rstudio/rsession.conf && \

that is talked about here and defaults to 120. Having said that i don't think this is the correct setting to configure to avoid the currently reported behaviour
