fix: Adding v0 import/export fields to dashboard metadata schema

[michellethomas]

SUMMARY

We see errors editing the metadata for dashboards that were imported using the v0 import/export feature. I'm adding those fields to the DashboardJSONMetadataSchema so we don't see those errors on validation. I'm adding these fields to the schema instead of removing them because the v0 import/export feature uses them.

I tested this change by editing a chart with these fields, let me know if there's anything else to test with this change.

TEST PLAN

I tested editing a chart that had these fields in the dashboard json_metadata.
