Description of Change

This updates the MAUI Aspire Service Defaults template to:

• use the current Aspire product name in the editable English localization source;
• link Service Defaults documentation directly to aspire.dev;
• link third-party notices directly to the current microsoft/aspire repository.

PR #32626 corrected the main template manifest but intentionally reverted localization files. This follow-up updates templatestrings.en.json, the editable source of the English localization metadata. Generated templatestrings.json, translated JSON files, and loc/**.lcl files remain unchanged so the repository's OneLocBuild workflow can generate the localization follow-up.

Issues Fixed

Follow-up to #32624 and #32626.

Validation

• Built and packed Microsoft.Maui.Templates.csproj.
• Verified the packaged English template metadata uses Aspire.
• Verified both replacement links resolve.
• Verified no editable .NET Aspire references or legacy Aspire links remain.
