chore: update prettier config

[janivo]

• Increase print width for better readability (see below for an example)
• Avoid parenthesis in arrow functions (e.g.: map(x => x.toString()) instead of map((x) => x.toString()))

Before:

componentDidLoad() {
    this.snackbarInstance = new MDCSnackbar(this.snackbarElement);

    this.snackbarElement.addEventListener(
      'MDCSnackbar:closing',
      this.handleSnackbarHide,
    );
    this.setupTimeout();
    if (this.stayVisibleOnHover) {
      this.snackbarElement.addEventListener(
        'mouseenter',
        this.interruptTimeout,
      );
      this.snackbarElement.addEventListener('mouseleave', this.setupTimeout);
    }
    this.snackbarInstance.open();

    if (this.message) {
      console.warn(
        '[ino-snackbar] The attribute "message" is deprecated, please use the default slot instead.',
      );
    }
  }

After:

  componentDidLoad() {
    this.snackbarInstance = new MDCSnackbar(this.snackbarElement);

    this.snackbarElement.addEventListener('MDCSnackbar:closing', this.handleSnackbarHide);
    this.setupTimeout();
    if (this.stayVisibleOnHover) {
      this.snackbarElement.addEventListener('mouseenter', this.interruptTimeout);
      this.snackbarElement.addEventListener('mouseleave', this.setupTimeout);
    }
    this.snackbarInstance.open();

    if (this.message) {
      console.warn('[ino-snackbar] The attribute "message" is deprecated, please use the default slot instead.');
    }
  }

Do we want to update all files according this configuration? Or do it splitwise by changed files?
