any_prefix_match differs from doc

[ericjkao]

Short description

In OPA 0.44.0, the new strings.any_prefix_match behaves differently from docs.
Docs say:

Returns true if any of the search strings begins with any of the base strings.

But in fact, strings.any_prefix_match({"x-0, z-0"}, "z-") evaluates to false contrary to the doc.

Steps To Reproduce

https://play.openpolicyagent.org/p/G5VMwfeI6s
See lines 11 and 14.

Expected behavior

According to doc and the motivating example in issue, both lines should evaluate to true.

Additional context

Strange that this bug exists and does not fail this test case:

opa/test/cases/testdata/strings/test-anyprefixmatch.yaml

Line 3 in e7130a8

strings: ["a/b/c", "a/b/d", "e/f/g"]

Hmmm.

{"x-0, z-0"}

☝️ This is a set containing of one string: "x-0, z-0". Did you mean to use

{"x-0", "z-0"}

a set of two strings, by any chance? 🤔

BTW we really need more examples in the docs, #4623

Oh lol that's a hilarious mistake on my part!
