Embed query param for self-hosted

[jam3smay]

Hi. Maybe I'm missing something, but I don't see any way to set the embed=1 query parameter which is necessary when using a self-hosted drawio server. Without the embed query parameter, the Save and Exit buttons will never display. Instead I only get a "Share" button.

I've verified that conditionally adding the embed parameter when baseUrl is present solves the problem. I'm happy to submit a PR for this but I wanted to check first to make sure I'm not overlooking something obvious.

Thanks for pointing this out! I also found the embed=1 parameter in the documentations, but everything seemed to work as expected without the parameter.

I just released a new version with the embed=1 parameter always included!

Thanks Marc! The component is very well done.
