Support wildcard in jsonpath

[lepapareil]

i create a simple fake api returning a json collection with netcat on port 8080:

$ while true ; do
  {
  echo -e "HTTP/1.1 200 OK\n\n"
  echo '{ "items" : [ { "item" : "a" } , { "item" : "b" } ] }'
  } |  nc -vl 8080 -q 1
done
Listening on [0.0.0.0] (family 0, port 8080)

i first request it with curl and jq to check that the json response is valid:

$ curl --silent http://localhost:8080 | jq -r .items[].item
a
b

i create a test.hurl file with a jsonpath collection assert (validated with external tools):

GET http://localhost:8080

HTTP/1.1 200

[Asserts]
jsonpath "$.items.[*].item" includes "a"

i run hurl

$ hurl --version
hurl 1.1.0

$ hurl test.hurl --verbose

 6 | jsonpath "$.items.[*].item" includes "a"
   |          ^^^^^^^^^^^^^^^^^^ the jsonpath expression '$.items.[*].item' is not valid
   |

i try with another valid jsonpath such as "$.items.[]item" but got the same error ... something seems to be wrong with the jsonpath parser used in hurl because I get the same error even using your documentation example at https://hurl.dev/docs/asserting-response.html#jsonpath-assert:

error: Invalid jsonpath
  --> hurdev-jsonpath-example.hurl:9:10

 9 | jsonpath "$.slideshow.slides[*].title" includes "Mind Blowing!"
   |          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ the jsonpath expression '$.slideshow.slides[*].title' is not valid
