Skip CSFR token check in LTI 2 tool settings service
Skip CSFR token check in LTI 2 tool settings service

Closes PLAT-3998

Test Plan:
Verify CSRF token check is disabled in both LTI 2 tool settings
service endpoints (update and show)

This check is not needed since we do LTI 2 API token checks in
these actions.
