[Settings] Make attribution links localizable

[niels9001]

Summary of the Pull Request

Moves Settings attribution link text into localized resources so Turkish and other locales can translate grammatical wording while preserving contributor and product names. Also makes the technical term "Stereolithography" translatable.

Detailed Description of the Pull Request / Additional comments

The affected attribution labels were hard-coded in XAML, preventing the localization pipeline from translating text such as "and other original contributors." Each label now uses an x:Uid resource, with translator comments that explicitly identify contributor, product, and file-format names that must remain unchanged. Links containing only a person or product name remain hard-coded.

The locked Stereolithography resource is also unlocked because it is a translatable technical term rather than a name.

Validation Steps Performed
