### Description

The parsing of params in parameterized ES|QL queries appears to be inconsistent with the parsing of non-parameterized ES|QL queries. Some examples on current main:

- ```
  {"query": "row a = 1 | eval x = now() + ?", "params": [{"type":"time_duration", "value":"5 hour"}]}
  ```
  results in the following exception:
  ```
  "type":"parsing_exception","reason":"line 1:23: Cannot cast value [5 hour] of type [KEYWORD] to parameter type [TIME_DURATION]"}],"type":"parsing_exception","reason":"line 1:23: Cannot cast value [5 hour] of type [KEYWORD] to parameter type [TIME_DURATION]"
  ```
- ```
  {"query": "row a = 1 | eval x = now() + ?", "params": ["1 week"]}
  ```
  results in
  ```
  "type":"verification_exception","reason":"Found 1 problem\nline 1:22: [+] has arguments with incompatible types [DATETIME] and [KEYWORD]"
  ```
- ```
  "query": "row a = 1 | eval x = now() + ? week", "params": [1]
  ```
  results in
  ```
  "type":"parsing_exception","reason":"line 1:32: extraneous input 'week' expecting <EOF>"}],"type":"parsing_exception","reason":"line 1:32: extraneous input 'week' expecting <EOF>"
  ```

All the queries work fine if the `?` is manually substituted with the given parameter.

The first two indicate that the parsing of query parameters is not consistent with our normal parsing, type resolution and verification pipeline.

According to @astefan , `version` is affected in a similar way.
