eslint: if projectService is used, project should be removed

[evoactivity]

Currently you will receive a lint warning if both are used together.

Docs show to remove it when projectService is used.

Not sure if that one failure is related, I wouldn't have thougt so :/

Seems the failing test is related to this
embroider-build/embroider#2609

Fyi: we have recenty readded project: true in app blueprint cause of issue with eslint and imports with file extension gts

ember-cli/ember-app-blueprint#126

Now i think you have broken in addon this... we need to patch this and other lines in eslint-parser:

addons require extensions -- so is there anything to still fix here?

i think the change of @evoactivity are good and should be done also inside app blueprint, but before we do this in app, we need to patch ember-eslint-parser...

I can confirm, that now i have the same issue in addon 😭:

To fix this => we should landed this as patch: ember-tooling/ember-eslint-parser#142
