fix(ionic-angular): drop eslint config update

[edbzn]

When running the @nxext/ionic-angular:application generator on Nx v19.8.0 the generator fails to update the ESLint config.

NX   Cannot find apps/test/.eslintrc.json

The reason is that Nx generates an ESLint config in JS instead of JSON. The format of the file is very different from the JSON one so instead of trying to patch the updateEslintConfig function to make it work with the new format, I rather decided to remove the function completely to keep the code as simple as possible. Let me know if you think it's better to support the .js format.

I'm not sure they're still relevant. The expected eslint config is from years ago, the format changed a lot in that time
