Replace ember-engines.com references with GitHub repository URL

[Copilot]

The ember-engines.com domain has been lost and now points to an unrelated AI content site. Updated all references to use the GitHub repository URL instead.

Changes

• Updated assertion message in LinkTo component validation
• Updated corresponding test assertion strings in routing tests

// Before
'See https://ember-engines.com/docs/links for more info.'

// After  
'See https://github.com/ember-engines/ember-engines/ for more info.'

Files changed:

• packages/@ember/-internals/glimmer/lib/components/link-to.ts
• packages/@ember/-internals/glimmer/tests/integration/components/link-to/routing-angle-test.js
• packages/@ember/-internals/glimmer/tests/integration/components/link-to/routing-curly-test.js

Original prompt

Find and replace any references to 'ember-engines.com' throughout the repository, including documentation comments and test assertion strings, with 'https://github.com/ember-engines/ember-engines/'. Where 'ember-engines.com' is used as a link, update the href to point to the GitHub repository. Where it appears in documentation or assertions, update the text accordingly. Add a note to the PR description that this is due to the domain having been lost and now belonging to an unrelated AI content site.
