The Alpine Linux team has enabled Java support for LibreOffice on ARM
architecture:
74d443f479
This commit is included in 7.5.5.2-r2, so the installed LibreOffice
package should be 7.5.5.2-r2 or higher to fix this issue.
However 3.18 doesn't have the 7.5.5.2-r2 package:
https://pkgs.alpinelinux.org/package/v3.18/community/aarch64/libreoffice
The Dangerzone image uses the alpine:latest image which is 3.18 as of
writing this.
For this reason, we switch to the edge repo of Alpine Linux, which
includes this fix.
