Adds usage example for uniqUpTo. 
A [user on Twitter](https://twitter.com/Dan_The_Goodman/status/1731453529078796740) pointed out that we didn't have a usage example here. This adds an example, and clarifies what `uniqUpTo` does.

Add more doc examples for the EXISTS operator 
The existing documentation for EXISTS makes it look like it only works
as part of a WHERE clause, when in fact, it can be used in many places.
Changing the docs to note that a bit differently with another example
should provide more clarity on the use of this term.

a85cf758b0 Fuzz JSON table function 
Create a table function `fuzzJSON`

An example query:
```
CREATE NAMED COLLECTION json_fuzzer AS json_str={};

SELECT *
FROM fuzzJSON(json_fuzzer, json_str = '{"students" : ["Alice", "Bob"]}', random_seed = 666, max_output_length = 128, probability = 0.9)
LIMIT 3

Query id: 7f802052-efb0-41b4-87fa-03b7dd290e9d

┌─json──────────────────────────────────────────────────────────────────────────────────┐
│ {"ade0yX":[9200406572736542991, true, "sm"]}                                          │
│ {"students":["Alice", "eSN3WO#a6NYTBe0$#OWwyIQ"], "cVoP2BuQugQ":17384271928263249403} │

└───────────────────────────────────────────────────────────────────────────────────────┘
```

Next step:
* Generate invalid string

Fixes #35962

add Object('json')

use named collection

315906b380 Add ability to parse hours/months without leading zeros 
Recently I was looking into one dataset, that has such format.

So I've changed the meaning of the following formatters for
formatDateTime()/parseDateTime(), like in other implementations [1]:

- %l/%k - to handle hours without leading zeros
- %c - handle months without leading zeros

  [1]: https://www.php.net/strftime

And since this is kind of behaviour change (even though it is unlikely
will break something), there is a new setting to control this new
behaviour:
- parsedatetime_enable_format_without_leading_zeros=1 (default ON)
- formatdatetime_enable_format_without_leading_zeros=0 (default OFF, since this could change users output)
