Is your feature request related to a problem? Please describe. I version control all *.drawio.xml in git. What frustrates me is that just saving without changing anything the modified attribute in XML is changed, and subsequently causes a change in local git.

Describe the solution you'd like It'd be nice to provide an option to strip information like modified out of the XML file to be version controlled.

Describe alternatives you've considered Manually removing the attribute, but it's tedious.

Additional context If you open a code in IDE, saving without changing anything wouldn't cause a change in git.
