single file change for to sql and from sql plugin

[lastlink]

Notes:

• I know this will be rejected since this is close contribution
• I've updated this from the prs so all you have to do is update the plugin src/main/webapp/plugins/sql.js file to install it locally.
• I'm aware that using a native tool for your db may be better for uml diagrams.
• There are many workflows that this works, you can do code share from vscode for collaboration after importing your drawio file from a sql table schema export
• It's easiest to setup in the drawio desktop, to use the plugin https://github.com/jgraph/drawio-desktop
  • git clone --recursive https://github.com/jgraph/drawio-desktop.git 1 gb clone btw
  • npm install
  • update drawio/src/main/webapp/plugins/sql.js with changes from branch
  • npm start run application
  • add plugin in Extras > Plugins > Add select sql
  • close application and reopen. Plugin is installed
• you can find the menu buttons in File > Export As > To SQL or Arrange > Insert > From SQL

We'll look into whether an exception can be made here as it's a significant amount of work to be rejected.

I ran through this process but the To SQL option was not showing up on the menu

@steel198513 try looking in File > Export As

@karthiart did you pull/copy the updates for the file from this pr? Otherwise you won't have my changes.
