ci: Update Meson to 0.52.1 in fedora docker

This is required to be able to build the doc. The debian docker is still
pinned to 0.49.2 which ensure we can build with both versions of meson.

Meson 0.52.0 warns about adding -Wall flag manually, we can remove that
because warning_level=1 (the default) option already implies it.
