ci: create cache for translate test data

[romanc]

Description

Recent (planned) downtime of NCCS portal showed a whole in our translate test data caching strategy. When we run pyFV3 or pySHiELD tests as re-usable workflow in e.g. NDSL tests, we don't cache the translate test data. This PR suggests to change that. The PR depends on

• ci: make "create cache" a reusable workflow pySHiELD#69
• ci: make "create cache" a reusable workflow pyFV3#91

to provide re-usable workflows for translate test data caching.

How has this been tested?

Tested on my fork, e.g. romanc#5.
