Add missing provide for LibreOffice on Fedora

[thmo]

Trying to replace the Fedora JDK RPMs with the adoptium provided, this requirement is not satisfied:

libjvm.so()(64bit) is needed by (installed) libreoffice-ure-1:24.8.4.2-2.fc41.x86_64

I guess LO should work with temurin-21, and it contains the libjvm.so:

$ rpm -ql temurin-21-jdk  | grep libjvm
/usr/lib/jvm/temurin-21-jdk/lib/server/libjvm.so

but misses the virtual provides that the Fedora LO package expects:

$ rpm -q --provides temurin-21-jdk | grep jvm
# no result

A small test (force-removing java-21-openjdk-headless) shows that LO finds "Eclipse Adoptium" as JRE and extensions still seem to work.

Related to #848.

The provides of in-jdk libraries is tricky: https://src.fedoraproject.org/rpms/java-21-openjdk/blob/f40/f/java-21-openjdk.spec#_391
