Update all .po files

[milotype]

• changed the first section of the header for every language to make them more uniform
• updated all .po files with the current .pot file, so now all files have 153 strings
• deleted all old/obsolete strings
• added string translations in obvious cases without knowing/speeking all languages. For instance: if the string "RGB Format" existed, I added translations for the new strings "Oklab Format", "Oklch Format" according to the translation for "RGB Format". In the case of "Copy Oklab" and "Copy Oklch", I used the same translation for the word "Copy" as in "Copy RGB" used in the specific language.
• added "translations" for the strings "Oklab" and "Oklch"
• the spanish translation is based upon the not yet released version of the user "IngrownMink4" (PR Update es.po #84)
• changed the "Eyedropper" app name in the Croatian translation ("Pipeta" is better then "Kapaljka")

@FineFindus In future I will make separate commits, I promise :-)

But in this case I've done several changes in all .po files at once per GitHub, because the component Eyedropper at Hosted Weblate is currently locked for all languages.

Maybe you can merge my changes for all files in this commit nevertheless and then apply them in Hosted Weblate?! I'm not a programmer, so I don't really know about the procedures between GitHub and Hosted Weblate :-(

I'm not sure what you mean by this.

Concearning my message: added "translations" for the strings "Oklab" and "Oklch"

#: src/widgets/preferences/preferences_window.rs:413
msgid "Oklab"
msgstr "Oklab"

#: src/widgets/preferences/preferences_window.rs:414
msgid "Oklch"
msgstr "Oklch"

It means that I've simply copied those two strings unchanged in every .po language file, because the source strings shouldn't be tanslated.

Please also check my isue #105.

Sorry, but I'm not going to merge this as a single commit. You can use git reset --soft HEAD~1 to reset the entire commit and then commit again, or use git rebase --interactive HEAD~1.

Sorry, I'm not a programmer (just a translator) and I don't know how to do what you suggest. :-(( Can you or someone else maybe do what is needed to resolve it? I think the project would benefit if my changes would be merged.

Thanks.
