Invalid Sink URI CloudEvent test sometimes includes quotes

In the logs for the latest pipeline nightly we saw a failed unit test
for CloudEvents with the following message:

```
TestSendCloudEvent/send_a_cloud_event_with_invalid_sink_URI:
cloudevent_test.go:106: I expected an error like invalid_URI:
unsupported protocol scheme, but I got Post "invalid_URI": unsupported
protocol scheme ""
```

It appears that sometimes the "invalid_URI" part of the error message
will include quotes, and sometimes (like when running locally) it won't.

This PR updates the regex to allow for these quotes in the error message.

Spelling fixes in our doc

Found using `mdspell -a -n --en-us "**/*.md"`. At some point we might want to have a built in ignore dictionary to avoid false positives.

Resolved result ref order can affect unit test outcome

Test TestTaskParamResolver_ResolveResultRefs performs a diff on a slice
of resolved result references. Unfortunately the ordering of this slice
is not guaranteed so sometimes the test fails.

This PR updates the unit test to check each entry appears as expected in
the tt.want slice (confirming also that the lengths of the slices
match). Also adds a small helper func to format the resolved result refs
for printing in the event that they don't match.
