Fix logic for password field content description

Simplify the conditional logic used to set the `contentDescription` for the `BitwardenPasswordField`.

The previous implementation used a double negative (`takeUnless { !showPassword }`) to determine if the password text should be exposed to accessibility services. This change replaces it with the more direct and readable `takeIf { showPassword }`, ensuring the content description is only populated when the password is explicitly visible.
