Bump json-patch to 4 use bundled jsonptr to 0.7

[clux]

replaces #1701 and #1696.

These would originally need to be upgraded together.
But now json-patch re-exports jsonptr now so we can get rid of the direct dep (which is very rarely used).

Doing it this way means we don't have to take a pin on jsonptr and just use whatever json-patch is using, and hopefully we'll get less dependabot errors.
