remove operation does not fail when the target does not exist

[oktoberfest6]

Hi,

according to https://datatracker.ietf.org/doc/html/rfc6902/#section-4.2
"The target location MUST exist for the operation to be successful"

If the target location does not exist the current implementation does nothing (which is good) but does not fail (which is bad).

local jsonpatch = require('jsonpatch')

local o = { key = "value" }

local operations = {
	{ op = "remove", path = "/otherkey", value = "othervalue" },
}

print("object before")
for k,v in pairs(o) do print(k, v) end
print("err:", jsonpatch.apply(o, operations))
print("object after")
for k,v in pairs(o) do print(k, v) end

result of execution

object before
key	value
err:	nil
object after
key	value
