Describe the bug

When making mermaid sequenceDiagram and using actors (stick figures) instead of participants (plain boxes) preview fails to parse diagram.

To Reproduce

1. Use mermaid example code to see that mermaid is parsing at all

```mermaid
sequenceDiagram
    participant Alice
    participant Bob
    Alice->>John: Hello John, how are you?
    John-->>Alice: Great!
    John->>Bob: How about you?
    Bob-->>John: Jolly good!

2. change any 'participant Alice' to 'actor Alice'
3. get parsing error:

Parse error on line 2:
...gram    actor Alice    participant Bob
----------------------^
Expecting 'SOLID_OPEN_ARROW', 'DOTTED_OPEN_ARROW', 'SOLID_ARROW', 'DOTTED_ARROW', 'SOLID_CROSS', 'DOTTED_CROSS', got 'NL'

Expected behavior

Box Alice changed to stick figure Alice as per mermaid documentation

Hi, note that dendron is in maintenance mode so nothing is likely to get fixed, but it seems that you can use either all actor declarations, or all participantones.

To (mostly) support both, you can declare the actors, but just implicitly start referring to the participants - now you give up on explicit ordering, but it's better than nothing
