chore: bump planx-core

[jessicamcinchak]

See theopensystemslab/planx-core#614

Testing notes:

• I've copied an "old" session from Bucks RAB production into this pizza database to confirm that the overview document maps display correctly
• Login to the pizza editor to generate an auth token then open this admin endpoint in your browser: https://api.4121.planx.pizza/admin/session/12c48901-178d-445d-a550-783a36ba4bc1/html
  • Confirm that you have the subtext "The user accepted the title boundary" and a grey code block "boundary" populated
  • There's CORS errors in the console related the the OS maps display that are consistent with production that we can fix forward later (this seems to be specific to the admin endpoint and local downloads are fine)
  • But the presence of the subtext & "boundary" block are confirmation that variables are linking up again when compared to prod endpoint https://api.editor.planx.uk/admin/session/12c48901-178d-445d-a550-783a36ba4bc1/html

I've additionally confirmed that sessions started and submitted today (so only new data fields present) are correctly displaying documents and maps - download 115c6638-f77a-40d4-a653-2dc1ea342214 from here to confirm https://editor.planx.uk/gateshead/report-a-planning-breach/submissions-log

Removed vultr server and associated DNS entries

Tested following the description in the PR (thanks!) and getting expected results.

Agree that the CORS issue is unrelated - it's possibly been there since day 1 of the /html route and will only effect PlanX devs testing.

These files were intended for local consumption so CORS aren't a consideration. If I download the file the map works as expected.
