feat(core): Add ESM support for Eslint config file

[ndcunningham]

This pull request includes changes to migrate ESLint configuration files from CommonJS (.cjs) to ECMAScript modules (.mjs) as the default.

ESLint Configuration Generation Changes

The changes also ensure consistent generated eslint configs based on the base eslint config.

• If the workspace root has an eslint.config.cjs or eslint.config.js with module.exports. When you create a library or application it will generate an accompanying config at path {projectRoot}/eslint.config.cjs of the same format.
• If the workspace root has an eslint.config.mjs or eslint.config.mjs with export default. When you create a library or application it will generate an accompanying config at path {projectRoot}/eslint.config.mjs.
• If no eslint config is found at the workspace root one will be created eslint.config.mjs
