Fix faulty translation key for covers

[devmarcstorm]

Description

I fixed the translation keys for covers from covers to cover in both currently supported languages (translations/en.json, translations/nl.json). See Issue #173.

Type of Change

Put an x in all boxes that apply

• New feature (non-breaking change which adds functionality)
• Bug fix (non-breaking change which fixes an issue)
• Hot fix (corrects a major software bug or fault and should released as quickly as possible.)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update
• Refactoring
• Security patch
• UI/UX improvement

Testing

I compiled the project, including the changes, via npx webpack --mode=production and tested the compiled mushroom-strategy.js on my Home Assistant instance. I confirmed that the cover strings are now properly displayed in the domain and area views.

Impact

I only changed the keys in the translation files, so the changes should not have any impact on the project outside of fixing the displayed strings.
