Latest LTS is incompatible with ember-cli v5.12.0

[mkszepp]

The latest EmberData package (v5.3.8) is not anymore compabile with latest ember-cli version (5.12.0).

This is because ember-cli has updated all dependency to latest.

When you try to create a new app you will run immediately into an error while build.

Steps to reproduce:

1. ember new my-app --embroider
2. ember s

Error:

Some V1 ember addons are resolving as incorrect peer dependencies. This makes it impossible for us to safely convert them to v2 format.

This occures because ember-data has in LTS no support for @ember/string v4.0.0

Fix

Backporting the allow of peerDependency as patch should resolve everythink for now, since ember-data is shipping next minor version

• Add @ember/string v4 to peerDependencies #9511
• Allow ember-inflector v5 as peerDependency & latest ember-inflector v4 version #9519
• Allow @ember/test-helpers v4 as peerDependency #9525

Workaroud

Apps must downgrade @ember/string for compatiblity or using overrides to fix this issue
