Cloning keycloak with a typical git configuration on Windows defaults to CRLF line endings in js/**/*.tsx files, yet Prettier is configured to require LF line endings. Some explanation in the GitHub docs - configuring git to handle line endings.

I'd like to propose two options which the Prettier docs also explain:

• Update .gitattributes with the specific *.tsx text eol=lf declaration (this would suggest Windows users re-clone the project).
• Update js/eslint.config.js with a "prettier/prettier": ["error", { endOfLine: "auto" }], rule.

The Prettier docs highlight that LF is enforced by default as of v. 2.0.0 which makes me lean towards updating the .gitattributes file. I have created the PR that accomplishes this here.
