[Bug]: ng add @o3r/eslint-config-otter adds Jest dependency for non-Jest projects

[vscaiceanu-1a]

Package name

eslint-config-otter

Package version

10.1.5

Reproduction steps

npm create @o3r otter-project
cd otter-project
ng g application webapp
# choose preset BASIC, NO Jest and NO Playwright when prompted
ng add @o3r/eslint-config-otter

Current result

Jest is added as dependency even if the project does not use Jest.

Expected result

Jest shouldn't be added by the eslint-config-otter ng add command.

When adding eslint-config-otter on a project, we should first check is jest is installed. If not, we don't add eslint-plugin-jest.
When adding @o3r/testing we should check if eslint-config-otter. If it is the case, we should add eslint-plugin-jest.
