Update dockerfiles to use bullseye

[luistoptal]

Pull request for issue: #376

Important: I'm not knowledgeable about devops so I made these changes somewhat in the dark, just to not get stuck and be able to move forward with other tasks, that is why I encourage careful evaluation by a devops engineer whether this should be merged or not, and I also provide steps to replicate / revert it.

The changes can be summarized as:

• updated debian distro everywhere (find and replace)
• run up.sh and fixed console errors until "it worked"

This PR updates the docker files to make use of debian bullseye. What problem does it solve?

Initially I encountered this issue when running ./up.sh

E: The repository 'http://apt.postgresql.org/pub/repos/apt buster-pgdg Release' does not have a Release file.

Looking at https://apt.postgresql.org/pub/repos/apt/dists/ it looks like the buster repo is no longer available, also this post suggests that buster is EOL / deprecated https://www.postgresql.org/message-id/Zqj_4nlZEqfbQ2aM%40msg.df7cb.de

I replaced all instances of buster by bullseye in the entire codebase, then I run the up.sh script again, and run into this error:

0.841 Err:3 http://security.debian.org bullseye/updates Release
0.841   404  Not Found [IP: 151.101.66.132 80]

which indicates that the bullseye/updates repo does not exist. To fix it I replaced the next code in fuw/docker-pure-ftpd/Dockerfile

ENV DEBIAN_FRONTEND noninteractive
RUN echo "deb http://http.debian.net/debian bullseye main\n\
deb-src http://http.debian.net/debian bullseye main\n\
deb http://http.debian.net/debian bullseye-updates main\n\
deb-src http://http.debian.net/debian bullseye-updates main\n\
deb http://deb.debian.org/debian-security bullseye-security main\n\
deb-src http://deb.debian.org/debian-security bullseye-security main\n\
" > /etc/apt/sources.list

The next error indicates missing deps

=> ERROR [ftpd builder 3/4] RUN apt-get -y update && apt-get -y --force-yes --fix-missing install dpkg-dev debhelper && apt-get -y build-dep pure-ftpd

So in file fuw/docker-pure-ftpd/Dockerfile I replace the following code:

RUN dpkg -i /tmp/pure-ftpd/pure-ftpd-common*.deb && \
  dpkg -i /tmp/pure-ftpd/pure-ftpd_*.deb || true && \
    # dpkg -i /tmp/pure-ftpd/pure-ftpd-ldap_*.deb && \
    # dpkg -i /tmp/pure-ftpd/pure-ftpd-mysql_*.deb && \
    # dpkg -i /tmp/pure-ftpd/pure-ftpd-postgresql_*.deb && \
  apt-get update && apt-get -f install -y && \ # added this so dependencies are fetched
    rm -Rf /tmp/pure-ftpd

After that, the up.sh script worked and the site was accessible locally

How to test?

Run the up.sh script

How have functionalities been implemented?

Any issues with implementation?

This PR "works" at least to avoid getting stuck and I believe it should not affect other features in case this PR is not used or replaced by something else
