chore(i18n): remove redundant ar_EG translations, keep ar

[BLumia]

The ar_EG (Egyptian Arabic) translation files are redundant variants of the existing ar (Arabic) translations. All build systems use glob patterns to collect .ts files, so removing these files has no impact on the build. The corresponding *_ar.ts files remain in place.

Files removed:

• plugins/dde-dock/translations/dde-dock_ar_EG.ts
• plugins/dde-network-display-ui/plugins/dock-wirelesscasting-plugin/translations/dock-wirelesscasting-plugin_ar_EG.ts

See: DDE-333

Summary by Sourcery

Enhancements:

• Remove redundant Egyptian Arabic translation files while retaining the shared Arabic translations.

Reviewer's guide (collapsed on small PRs)

Reviewer's Guide

This cleanup removes two redundant ar_EG translation files; because translation discovery uses .ts globs and the canonical Arabic files remain, build and Arabic localization behavior should be unchanged.
