Issue with filtering by comparison

[dpopp07]

The Go package does not seem to properly execute comparison queries. For example, if I have data:

{
  "resources": [
    {
      "description": "old",
      "updated_at": "2023-04-05"
    },
    {
      "description": "new",
      "updated_at": "2024-03-06",
    }
  ]
}

and execute query

resources[?updated_at > '2024-02-01']

the filtered result should only include the "new" resource. When I run this same example in the playground on the JMESPath site, I see the behavior I expect. When I run this in my Go code, I receive no results back from the search. Clearly, something is wrong in the Go code.

Also see the related issue against the original repo.
