* lisp/progmodes/typescript-ts-mode.el(typescript-ts-mode): Add indentation
rule for switch case and default keywords.

Bug: `typescript-ts-mode` is missing indentation rules for 'case' and
'default' keywords in switch statements.

Recipe to reproduce:
Copy the following code into a buffer:

    const foo = (x: string) => {
      switch (x) {
                  case "a":
                  console.log(x);
                  return 1;
    case "b":
      return 2;
                  case "c":
                  default:
                    return 0;
      }
    };

And call the following function to configure typescript-ts-mode and
indent the buffer

    (defun my-ts-indentation ()
      (interactive)
      (setq indent-tabs-mode nil)
      (setq typescript-ts-mode-indent-offset 2)
      (typescript-ts-mode)
      (indent-region (point-min) (point-max)))

The indentation for the 'case' and 'default' branches within the switch
statement should still be unchanged due to missing indent rules.
Bug applies to emacs 29 as well.
