PDF/CSV export

I am having issues with PDF export on icingaweb2 pages (does not work out of the box).
Enabling the PDFexport module google-chrome is needed in the docker image. Can this be added as default to the Dockerfile?

Dokerfile diff
`-RUN ["bash", "-exo", "pipefail", "-c", "export DEBIAN_FRONTEND=noninteractive; apt-get update; apt-get install --no-install-{recommends,suggests} -y apache2 ca-certificates libapache2-mod-php7.4 libldap-common locales-all php-{imagick,redis} php7.4-{bcmath,bz2,common,curl,dba,enchant,gd,gmp,imap,interbase,intl,json,ldap,mbstring,mysql,odbc,opcache,pgsql,pspell,readline,snmp,soap,sqlite3,sybase,tidy,xml,xmlrpc,xsl,zip}; apt-get clean; rm -vrf /var/lib/apt/lists/*"]

+RUN ["bash", "-exo", "pipefail", "-c", "export DEBIAN_FRONTEND=noninteractive; apt-get update; apt-get install --no-install-{recommends,suggests} -y wget apache2 ca-certificates libapache2-mod-php7.4 libldap-common locales-all php-{imagick,redis} php7.4-{bcmath,bz2,common,curl,dba,enchant,gd,gmp,imap,interbase,intl,json,ldap,mbstring,mysql,odbc,opcache,pgsql,pspell,readline,snmp,soap,sqlite3,sybase,tidy,xml,xmlrpc,xsl,zip}; wget -q https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb; apt-get install --no-install-recommends -y ./google-chrome-stable_current_amd64.deb; rm google-chrome-stable_current_amd64.deb; apt-get clean; rm -vrf /var/lib/apt/lists/*"]`

The downside is that the image size jumps from around 700MB to 1.1GB

Start by inspecting the Dockerfile install step and the PDFexport module requirements described in the issue. Build the image and verify that PDF export works without manual browser installation, while checking the reported image-size increase; the CSV portion of the title is not specified.
