Thank you for providing and maintaining this action.
I would like to request support for European Portuguese (pt_PT) dictionaries. At the moment, the documentation mentions support for English, French, German, Italian, Spanish, Russian and Ukrainian, via both Aspell and Hunspell, but Portuguese is not listed.
There are dictionary packages for European Portuguese available in common Linux distributions for both Aspell and Hunspell. Adding pt_PT would allow projects written primarily in European Portuguese to use this action.
Thank you in advance for considering this feature.
