[Reminder] Check regularly if concept in template template parameters are supported by all compilers
In #1852 (closed), I found out that new code was not properly accepted by gcc, and that is was an identified issue that was solved... but not incorporated before gcc 13.2.1.
And both Ubuntu (even with the PPA) and Honebrew on macOS provides an earlier version.
I have introduced a macro MOREFEM_WITH_TEMPLATE_TEMPLATE_CONCEPT_SUPPORT which essentially resolves to class
currently but could be replaced by the template template with concept, which was already supported by AppleClang and clang in Linux.
