Add Export as SVG option in db.build

[Ebrahim-Ramadan]

the db.build service is great, but devs may get to craft a schema for preview or quick docs, so a Export as SVG button, that creates pdf or svg page of the tables and their relations view, might just be a great feature

Hi @Ebrahim-Ramadan, thank you for opening this issue. As this is a feature request I'm going to move the issue over to discussions/enhancements but again thank you for opening.
