ci(retro): switch to sp04 for 252

[PProfizi]

This PR switches to 252.sp04 as last released version of DPF.
It switches to using project action variables made of maps as building the combinatory by hand at runtime becomes complicated.
We switch to two new repository variables (to not break current behavior):

ANSYS_VERSIONS_RETRO_WITH_PATCH = [ {version: "251", patch: ""}, {version: "242", patch: ""}, {version: "241", patch: ".sp01"}, {version: "232", patch: ""}, {version: "231", patch: ""}, {version: "222", patch: ""} ]
and
ANSYS_VERSION_LAST_RELEASED_WITH_PATCH={version: "252", patch: ".sp04"}

Release CI run (failures here are already present for main)
