Angular Library generator creates wrong eslint config with eslint.config.cjs at project root

[LWC241]

Current Behavior

I am using "type": "module" in my package.json and have an eslint.config.cjs instead of eslint.config.js file at the root of my project.

When I try to create a library with the @nx/angular:library generator, the generator correctly finds the config file, but generates only a barebones eslint.config.js file in the new library:

Expected Behavior

The generator should generate an eslint.config.cjs file and use the longer base config that it would generate with an eslint.config.js file at project root.

Additional Information

I have looked into the code a bit and believe this may be an issue with the addLintingGenerator, as it will always generate an eslint.config.js file. There also is already a constant eslintFlatConfigFilenames, but it is not used when checking if the additional code should be added to the newly generated config file.

I would also be happy to try to make a PR for this.
